High Precision 3.9pF 50V C0G (NP0) 0402 MLCC Capacitor for RF Tuning and Frequency-Critical Circuits
This 3.9pF multilayer ceramic capacitor in a compact 0402 SMD package is designed with C0G (NP0) dielectric, offering exceptional stability and low-loss performance for high-frequency applications. With a 50V rating and tight ±0.25pF tolerance, it is ideal for RF tuning, impedance matching, and resonant circuits where precise capacitance control is essential. Its ultra-compact size makes it suitable for high-density PCB layouts in communication modules, RF systems, and precision electronic designs.
The C0G dielectric ensures near-zero capacitance variation across temperature and voltage, making this capacitor highly reliable for frequency-sensitive applications. With low ESR and a high Q factor, it delivers excellent performance in RF and microwave circuits with minimal signal distortion. It is widely used in oscillators, RF filters, antenna matching networks, and timing circuits where stable and repeatable electrical characteristics are critical.
