The CAP CER 3PF 500V C0G/NP0 1206 is a type of ceramic capacitor with specific characteristics. It has a capacitance value of 3 pF and tolerates up to ±0.1 pF variation in this capacity. This component also withstands voltages of up to 500 volts. The CAP CER is classified as a C0G or NP0 (negative positive zero) type, indicating its temperature stability properties. It is designed for use in the metric 1206 package size, which corresponds to the 3216 designation in some terminology.
