The causes and solutions of frequent damage to automotive sensors
1.The reasons for frequent damage to automotive sensors？
Leiiditech EMCLittle brother，Discovered during rectification of automotive customers，Frequent damage to vehicle sensors，The main common reasons：Unstable voltage。
During vehicle operation，Voltage fluctuations are unavoidable。These fluctuations can originate from the start of the engine、alternatorThe working status of and the use of other electrical equipment，Bringing huge challenges to the sensors in the car。Unstable voltage is a severe challenge for sensors，Because sensors require extremely high voltage stability。
2. Lei MaoEMCLittle brother provides a solution
Lei MaoEMCThe young man has found a feasible solution：Using small volume and large currentTVS（Transient Voltage Suppressor）Protective devices。TVSProtective devices can quickly respond and absorb overvoltage，Ensure that the voltage does not exceed the working range of the sensor。They have the characteristics of low voltage leakage and fast response，Effectively protecting sensors from voltage fluctuations。
