FAQ’s
Passive components store, resist or filter energy but cannot amplify a signal. Active components can amplify, switch or control signals and need a power source to operate.
These are parts built and tested to handle heat, vibration and long working hours in vehicles. Components that meet AEC-Q200 standards are a common choice for automotive use.
A MOSFET is a fast-switching transistor that controls power with very little energy loss. It is widely used in power supplies, motor drivers, inverters and vehicle electronics.
A switch is operated by hand, while a relay opens or closes a circuit automatically using an electrical signal. Relays are ideal for controlling high-power loads from a low-power circuit.
A PCB is a printed circuit board that holds components and connects them through copper tracks. Parts are placed on it using SMD or through-hole methods and then soldered in place.
