COG (NP0) Dielectric Features of KYOCERA AVX 04025A3R0CAT2A Ceramic Capacitor

At the core of the 04025A3R0CAT2A capacitor’s performance is its COG (NP0) dielectric material, classified as EIA Class I. Modern COG (NP0) formulations, leveraging neodymium, samarium, and other rare earth oxides, provide exceptional temperature compensation with minimal hysteresis effects. The major engineering benefit lies in the material’s capacitance change of only 0 ± 30 ppm/°C, resulting in less than ±0.3% capacitance variation from –55°C to +125°C. This stability, compared to standard film or Class II ceramic capacitors, makes the 04025A3R0CAT2A highly suitable for signal integrity and frequency-dependent architectures. Life drift is also kept under ±0.1%, ensuring long-term performance consistency.

Principal Electrical Characteristics of KYOCERA AVX 04025A3R0CAT2A Ceramic Capacitor
