The part number is CAP CER 15PF 100V C0G/NP0 1206. It corresponds to a specific type of ceramic capacitor with the following characteristics: capacitance of 15 picofarads (pF), tolerance of ±10%, and a maximum working voltage of 100 volts. The capacitor conforms to the C0G or NP0 temperature coefficient, which indicates it has a near-zero change in capacitance across a wide temperature range. This specific component is packaged in a 1206 (3216 Metric) case size.
