Application of chip capacitors in automotive electronicsIssuing Time : 2020-06-11
The reason why the professional chip capacitors for automobiles are special is because the chip capacitors professionally used in automobiles must meet the conditions of use. The fields of use for automotive special chip capacitors are: car lights (fog lights, headlights), dashboards, GPS navigation, Transmission indicator light, etc.
What is the difference between automotive chip capacitors and ordinary chip capacitors? Can ordinary chip capacitors be used in cars?
① Automotive-grade chip capacitors have passed AEC-Q200 certification, which improves the reliability of product quality, and ordinary chip capacitors do not have such certification. In terms of reliability, it can no longer be used in cars.
②The components used in automobiles have higher temperature requirements. The highest temperature of automotive chip capacitors can reach 150 ℃, while the maximum temperature of ordinary chip capacitors is 125 ℃. The testing temperature of automotive-grade chip capacitors is 85°C, and the testing temperature of ordinary chip capacitors is 40°C. The temperature requirements for chip capacitors used in automobiles are high, and ordinary chip capacitors simply cannot meet this requirement. Therefore, ordinary chip capacitors cannot be used in automobiles.
③The temperature cycle of automotive chip capacitors is 1000 cycles, and the temperature cycle of ordinary chip capacitors is 5 cycles. It can be seen that the service life of automotive grade chip capacitors is 200 times longer than that of ordinary chip capacitors.
