一、Capacitor

Capacitor is the ability of a component or circuit to collect and store energy in the form of an electrical charge The capacitance value of a capacitor is measured in farads (F)

 

二、Function

Their ability to store DC charge and to offer relatively low impedance to alternating frequency signals make them useful in power supply circuits and bypass applications.

 

三、How to order?

Key points: Material? Type? Density? DIP or SMD? Pressure resistance? Dimensions? Frequency characteristics? Polarity? Temperature resistance? Precision? Durable hours?
