A ceramic capacitor with the designation CAP CER 680PF 100V C0G/NP0 1210 has a capacitance of 680 picoFarads and operates at a voltage of ±100V. It is classified as a C0G or NP0 type, which indicates that it is a temperature-stable ceramic capacitor with minimal variation in capacitance over a wide range of temperatures. The physical dimensions are specified using the metric size 3225, equivalent to the standard 1210 size in the imperial system.
