The specified component is a CAP CER 3900PF 630V C0G/NP0 1812 ceramic capacitor. It has a capacitance value of 3900 pF with a tolerance of ±2% and can withstand a maximum voltage rating of 630 volts. This capacitor conforms to the C0G (NP0) specification, which designates it as a temperature-compensating type with minimal change in capacitance over temperature variations. The designation "1812" refers to its metric size, which is approximately equivalent to a 6.4 mm × 3.2 mm footprint, and the part number includes a reference to the metric system (4532) for clarity.
