The KC-LINK 2220 is a type of ceramic capacitor with a specific set of characteristics. It has a capacitance value of 0.1 microfarads (µF), a voltage rating of 500 volts direct current (VDC), and uses the C0G or NP0 material, which is known for its stability across temperature ranges. The capacitor's dimensions are metric 2220, equivalent to the standard 5750 size.
