The CAP CER 3PF 50V C0G/NP0 0201 is a specific type of ceramic capacitor. It has a capacitance value of 3 picoFarads with a tolerance of ±0.25 picoFarads and can withstand a maximum voltage of 50 volts. This component is part of the C0G, or NP0, family which is known for its stable properties over temperature variations, often used in applications requiring high precision. The 0201 designation refers to its compact size, being similar to the metric size 0603, making it suitable for use in surface mount technology (SMT) and other applications where space is limited.
