What's New at Firstohm

Spring 2020


spring5G related applications will drive the development of resistors toward the direction of "high reliability, high stability and high energy density". To meet the trend of integration of circuit boards, the demand for MELF resistors will increase significantly. In addition, with the popularization of new energy vehicles and the trend of the Internet of vehicles, the demand for vehicle grade resistors will also increase. We believe that starting from 2020, the demand for 5G communication and body electronics will continue to increase. Firstohm has begun to plan a new factory. Next year, its production capacity will grow by multiple times. Meanwhile, it is actively developing new products with "high reliability, high stability and high energy density".


Firstohm In Action

Do You Know

★ISO 16750-2-2012 5a, SGS Lab Test Results
The electronic products to be applied in the vehicle system must pass the EMC conduction transient test in accordance with ISO7637 or ISO16750, so as to ensure that the automotive electronic components will not fail under the effect of the surge. In view of the surge pulse endurance required by ISO16750#5a, TVS with a function level higher than #5b generally must be selected to pass the test. FIRSTOHM put forward the optimal vehicle specification solution for passing the test standard of #5a, that is, to use the surge resistance to reduce the impact of the surge on the circuit. Therefore, the SWM (anti-surge wire wound resistor) + 3KW/5KW TVS can be used to pass the #5a test. The benefit is shown in the table below:
