The CAP CER 56PF 1.5KV C0G/NP0 1206 is a specific type of ceramic capacitor. It has a capacitance value of 56 pF and is rated for operation at ±10% tolerance. The capacitor also has a voltage rating of 1500V or 1.5kV, which is suitable for high-voltage applications. Its construction is based on the C0G/NP0 ceramic material, known as NPO in the metric system (1B). The component's lead spacing corresponds to the 1206 package size, commonly referred to as the 3216 metric format.
