The specified component is a CAP CER 820PF 50V C0G/NP0 0402 ceramic capacitor with a capacitance of 820 pF and a voltage rating of 50V. It has a tolerance of ±5% and follows the C0G or NP0 temperature coefficient, commonly used in precision applications due to its minimal change in value over temperature. The component is packaged in a 0402 (1005 metric) size case.
