The CAP CER 620PF 50V C0G/NP0 0402 is a specific type of ceramic capacitor. It has a capacitance value of 620 picofarads (pF) with a tolerance of ±5% and can withstand a voltage rating of 50 volts. This component is part of the C0G, also known as NP0, family, which are well-known for their high stability over temperature. The 0402 size refers to its dimensions in metric units, corresponding to the 1005 designation in the more commonly used mil-spec format.
