World famous semiconductor manufacturers ROHM developed is very suitable for automotive, industrial equipment and communications infrastructure, such as easy to sulfide under the harsh environment of the use of new type sulfide resistant SMD resistor "SFR series" products.

SMD resistor internal surface of the electrode and side electrode commonly used is silver. But, the silver easy to cure, in sulfide environment problems when using the long-term reliability of the application. To this end, the series of products in the structure of electrode part adopts uniquely ROHM and protection of materials, greatly improve the performance of resisting sulfide successfully. Very help to boost the automotive and industrial equipment used in curing environment application of long-term reliability and security.

This series of products have been started mass production in 2015. Production base for ROHM Integrated Systems (Thailand) Co., Ltd. (Thailand) and ROHM Electronics Philippines, Inc. (Philippines).

In the future, ROHM will continue to improve in the field of SMD resistor has higher resistance to sulfide performance lineup, in order to improve the long-term reliability of various applications and security to contribute.

Background > <

Air is contained in automobile exhaust emissions, sulfur gases exist in various forms of sulfur content. The sulfur ingredient adhere to the metal surface will gradually caused sulfide. Resistance and other electronic components are often use silver. After long-term exposure to sulfur components, these components may be caused by electrode part of vulcanization resistance value changes, resulting in application of failure. In recent years, in the field of automotive and industrial equipment, etc, in order to improve the application of reliability and safety for a long time, against the vulcanization properties of demand is higher and higher.
