The Application of Automotive Grade Resistors

Writer:Microhm Page View:Date:2019-01-09
In many cases, to ensure the safe operation of electric vehicles, electric vehicle production companies will use special automotive grade resistors. This type of gauge resistor has many advantages over ordinary resistors. The car gauge resistors are mainly including network resistor, anti- sulphur resistor, current sense resistor, surface mount thick film resistor, surface mount thin film resistor.

The automotive grade resistors commonly used in automobile electronics has the following characteristics:
First, automotive grade resistor has high reliability and multi-layer electrode structure design in resistance production technology because of strict requirements;
Secondly, automotive grade resistor  is generally used in chip package mode and can be compatible with all welding processes;
Third, automotive grade resistor  is used in automobile electronics, so it must be reached the standard of
AEC-Q200.
Fourth, the most commonly used automotive grade resistor  is the thick film ones. The main models are 0201,0402,0603,0805,1206,1210,2010,2512 type.

At present, automotive grade resistor is more and more widely used in electric vehicle, which is closely related to the development of electric vehicle industry. Automotive electronics controller, wiper, automotive power, automotive taillights, motor vehicles and other products require automotive grade resistors. In addition, in the running process of electric vehicle, the precharge process of gauge level before the high voltage power up is very important, because the voltage at both ends of the electric control system is almost zero before the industrial electric control is switched on. If the maximum current generated by the instantaneous electrification of the equipment can easily cause damage to the equipment, the purpose of the series car gauge precharge resistance during the precharging process is to reduce the influence of the charging current.
