NP0 capacitors, also known as C0G capacitors, are primarily made from a formulation of temperature-compensating EIA Class I ceramic materials. These modern C0G formulations incorporate neodymium, samarium, and other rare Earth oxides, providing exceptional stability with a capacitance change of 0 ±30ppm/°C across a temperature range of -55°C to +125°C. The capacitance drift for C0G ceramics is negligible at less than ±0.05%, significantly outperforming other dielectrics, which can exhibit up to ±2% drift. This makes C0G capacitors ideal for applications requiring high stability and low hysteresis.
