What does an automotive capacitor do?

An automotive capacitor is a basic storage device used to store electrical charges and release them as it is required by the circuit. In a simple form, it is made of two conductive plates (Electrodes) and an insulating medium (Dielectric) that separates the electrodes.

What are automotive capacitors used for?

Lighting applications include HID/Xenon Headlights and LED Lights On Board Chargers for Electric Cars and Chargeable Hybrid Automobiles Sensors for System Monitoring of Drivetrain, Battery Management, Tire Pressure, etc. DC/DC Convertors for Converting 48VDC to 12VDC for motors and instrument systems Control Systems such as CAN Bus and Regenerative Stop/Start Battery Charging
