WAYON Vehicle Electronics

Protection SolutionProtection Solution

A life style which connects family with vehicle has become a new trend in automotive industry. The capability of installing consumer y p y gelectronics into vehicles is pushing the innovation of standard global interface. In this automotive control application, obviously circuit damage will be caused during the process of insert or extractcircuit damage will be caused during the process of insert or extract peripheral units or any other error condition. But PPTC or ESD components will avoid it effectively.
