The automotive grade fixed resistor is a new type of resistor. At present, many brands are competing in the field of automobile resistance. If the resistors are to enter the automobile industry, it is necessary to pass a test standard AEC-Q200. Why this standard is used to judge the resistors whether can be applied to automotive field?
The verification specifications of automotive electronics seem to be more stringent than those of ordinary parts. We have carefully confirmed that the main test conditions are still JEDEC or MIL-STD in the commonly used international standard AEC (Automotive Electronics Council).In addition, this part of the test method is built independently, so its thinking surface is more complete than the traditional IC. The success of AEC-Q200 third party test certification of automotive electronics industry standard marks a more complete range of automotive resistance products for this brand, which can be regarded as a solid foundation for the overall entry into the automotive electronics market.
The automotive grade resistors have the characteristic of ±25ppm/ ℃ ~ ±50ppm/ ℃ TCR and 0.1%～1.0% tolerance. Due to the special high temperature resistance film material and surface passivation technology, the product has excellent high temperature resistance and long-term stability. Resistors are tested in the environmental test conditions of AEC-Q200 constituting on the basis of MIL-STD-202 and JEDEC22A-104 specifications. The test temperature of different parts vary, and the requirements of applying power supply (voltage, current, load) will also be different. High temperature storage is not applied bias voltage and load, but at high temperature working condition, temperature cycle and temperature shock are needed to detect the stability of the gauge resistance.
At present, AEC-Q200 automotive grade resistors can be widely used in automotive electronics, medical instruments, testing / measuring equipment, printing equipment, automatic equipment controller, converter, communication equipment and so on.
