The CAP CER 5PF 500V C0G/NP0 1206 is a type of ceramic capacitor with specific characteristics. It has a capacitance value of 5 pF and a tolerance of ±0.25 pF, while it can withstand a maximum voltage of 500V. The designation "C0G" or "NP0" indicates that it belongs to the Class 1, NPO (or C0G) dielectric material group, often used in applications requiring stable capacitance over temperature changes. This particular capacitor is available in the 1206 metric package size, equivalent to the more commonly known 3216 package size.
