Passive components as the basic element, is a perennial market, the global electronics industry boom, driven resistance in emerging applications demand is. At the same time, face from industrial to consumer electronics, the application of resistor of high performance and miniaturization is the eternal pursuit.

Industrial and automotive electronic stringent requirements for resistance and challenges

"For resistor industrial and automotive electronic product requirements, than the general consumer electronics, mainly for product failure rate is low, after long time use the change of volume is smaller, and when using the product under the bad environment need to be able to function properly, namely environmental capacity is better." Light jie technology research and development manager said mechanisms.

Material for long time use is often due to the inadequacy of ability of resistance to environmental capacity and voltage surge appeared premature aging phenomenon, but in the industrial class and automobile electronic product grade, tolerance for the environment, also must increase of sulfur resistance function, in order to avoid terminal for sulfur sulfur gas and material produce flowers, causing the circuit problem. Light jie technology unique terminal protection technology, expand to automotive electronic level, improve the environment to use the tolerance on the automobile electronic parts ability, and enhance product for electricity generated by wave resistance ability, in the car on the application of power management and av equipment, can achieve good stability.

Skadden, science and technology co., LTD., senior engineer Yang Zhizhe parker thinks, at present, the industrial and automotive electronics applications, such as technical challenge resistor is in extensions and SMD resistor SMD resistor operating temperature of the cooling effectiveness of ascension.

Yang Zhizhe parsing, automotive electronics, for example,? In AEC - Q200 test specification, resistance class should be able to operate in - 40 ℃ to + 125 ℃,? But most of the thick film and thin film of SMD resistor power deduction of turning point is 70 ℃,? Within 70 ℃ the resistance of the power is to maintain the rated power, but the resistance power of more than 70 ℃ is the temperature rise and fall, this power for automobile electronic designers have to do the calculation of deduction, to maintain the resistance under the power of residual can safe operation. ? SEI in the future development of SMD resistor power point deduction can extend to + 125 ℃, beneficial to reduce automobile electronic designers in the deduction of computing power.

For SMD resistor, on the other hand, the cooling efficiency of the ascension, current detection of SMD resistor, for example,? Current detecting SMD resistor its low resistance to flow through a higher current, need higher power and larger size specifications, in order to meet the current through the higher current SMD resistor, electronic circuit designers tend to consider using larger high-power current SMD resistor or SMD resistor in parallel more than current detection, so a lot of room for the circuit board. More than current SMD resistor in parallel faults lies in the matching of needs computing parallel resistance, such as using different resistance to form parallel matching resistance value, which makes most of the current will flow through the low resistance current SMD resistor, causing most of the current hot uneven distribution of SMD resistor SMD resistor in the current detection, reduces resistance life.

Circuit board without any increase in resistance to occupy space and cost, under the consideration of the long end of electrode current detecting SMD resistor is skadden parker (SEI) the direction of the development of science and technology. We have successfully develop size 0612/1.5 W SMD resistor CSRF0612 foil current detection, with the same room for circuit board CSRF1206 / more than 1 W 0.5 W, higher current and better circulation increase resistance of thermal efficiency.

Vishay resistor products target market is a long-term stability and high precision requirements of automotive and industrial applications. Tan chess said, our product is with lead, tables, and array type packaging in the form. In addition, we also provide high pulse load; High pressure (such as MELF high-pressure); High precision, high pressure (such as TNPV high-pressure); Resistance to sulfur RCA/e3, and many other special series resistor. Industrial applications demand a higher surge and higher voltage. In automotive applications, especially in the applications of hybrid and electric vehicles, need more current. We have improved the high power thin film resistance and high current 600 a + shunt to meet these challenges.

The miniaturization of resistance is not volume

In the miniaturization of resistance, although there are 03015, but most of the manufacturers the minimal size products still for 01005. Tan chess said, the size of the resistor and may be smaller than in 01005, it is on the placement machine's ability. One option is to use chip resistor array, i.e. multiple resistor placed within a single package. A side benefit of the chip resistor array is its helps to reduce the circuit board space and the number of strips of motor, so as to save cost.

Skadden hodginsii technology (SEI) at present in thick film series SMD resistor consumer size is 01005, according to the miniaturization of wearable devices and micro mechanical application requirements of intelligent circuit, skadden will continue parker toward smaller size SMD resistor development. As for towards what small size, Yang Zhizhe said, is on the basis of the cooperation of customer circuit board size and the intensity of the circuit board components.

For improve product miniaturization and product features, has always been one of light jie technology development strategy. Mechanisms that, although the minimum size of the product of 01005 type, but this is not a physical limit, our current research and development capabilities have been able to produce more small parts, but there is no related to the market demand, also do not have the corresponding production equipment can be used, the client has yet to have to use smaller parts corresponding to the machine and equipment, and so at this stage the smallest parts still for 01005. But now believe each related equipment factory is also in the development of miniaturized parts needed for production equipment, when the market demand or related equipment mature, parts development is the trend toward miniaturization.

New energy and growth potential of unmanned aerial vehicle (uav)

According to the study, on the basis of Navigant Research company? With new energy car battery cars, for example, in the global market from 2014 to 2035, the growth rate of 72.4%, and 200 million new energy car, average annual growth rate reached 3.5%. The world of science and technology (SEI) parker product support for new energy vehicles, especially in terms of power battery current ready and launched a series of new energy vehicle power battery current sense resistor and high-power prefi lled resistance, to meet customer demand. ? In the future of new energy vehicle power battery and standby power battery etc. The use of growth period, the cypress technology (SEI) estimates of new energy vehicle current sense resistor and high-power prefi lled resistance average annual growth rate will be higher than 3.5%.

Currently skadden hodginsii technology (SEI) ESS Energy Storage System (Energy Storage System), the new Energy vehicle Power Battery Module (Power 'Module) and unmanned aerial vehicle (uav) (Drone) is more potential, SEI also engaged in related resistance products application development, especially in the current sense resistor. In terms of energy storage system ESS, we believe that the home energy storage system with the application of community type of energy storage system growth period, the relevant battery management circuit to measure current and power demand of current detection resistance is relatively large; In new energy vehicle Power Battery Module (Power 'Module) aspects as above described, and the perfection of every country in the new energy vehicle charging scheme, such as charging pile in the construction of building and the development of mobile wireless charging, related to the current resistance prefi lled with high-power resistance demand also gradually increased; In unmanned aerial vehicle (uav) after our skadden cypress (SEI) of the study of science and technology, an unmanned aerial vehicle (uav) the resistance of the rotor speed, four rotor unmanned aerial vehicle (uav), for example, USES 4 to 12 current SMD resistor, in today's unmanned aerial vehicle (uav) application vigorous development, the current demand of SMD resistor is relatively larger.

"We are currently locked in the Chinese market as our TuiGuangDian. The Chinese government under the strong support for new energy policy and the vigorous development of the unmanned aerial vehicle (uav) industry, for the future of science and technology (SEI) parker's current detection of resistance in this piece of business development, there will be a big help." Yang Zhizhe said.

Tan chess also believes that, in the future, robots, unmanned aerial vehicles and new energy will be the hot areas of research and development and application engineering. Market will continue to need high precision, with long-term stability, strong and durable and maintenance free products. Vishay's long-term strategy is to provide customers high quality and reliable electronic components.

"In the new energy vehicles, mainly for the Chinese market to promote this piece, but cars are not as general consumer electronics, able to quickly enter the market popularity, so can make much demand cannot clear, estimates that there is a new product launch will inevitably leads to the increase in demand." Mechanisms to further said, for example, iot wireless communication, smart home, wearable devices, wireless charging, automotive electronics, and new energy vehicles, and so on are all potential markets.
