A CAP CER 150 PF 3 KV NP0 RADIAL is a type of ceramic capacitor. This component has a capacitance rating of 150 picofarads with a tolerance of ±5% and can withstand voltages up to 3000 volts (3 kilovolts). It uses the C0G or NP0 dielectric material, which is known for its stability over temperature, making it suitable for applications requiring tight capacitance tolerances. The radial lead design allows for easy mounting on a printed circuit board (PCB).
