KYOCERA AVX 04025A3R0BAT2A

KYOCERA AVX 04025A3R0BAT2A Ceramic Capacitor Product Summary

The KYOCERA AVX 04025A3R0BAT2A is a surface-mount ceramic capacitor, specified at 3 pF with a tight tolerance of ±0.1 pF and rated for 50 V operation. Utilizing the C0G (NP0) dielectric, this capacitor comes in the compact 0402 (1005 metric) package, aligning with modern high-density board designs. Its nominal capacitance and construction make it ideal for circuits that demand minimal capacitance variation and high reliability—factors of critical importance in RF, high-frequency, and precision analog applications.

Dielectric Properties and Material Features of KYOCERA AVX 04025A3R0BAT2A

At the core of the 04025A3R0BAT2A is the C0G (NP0) dielectric, an EIA Class I ceramic formulation distinguished by its temperature-compensating properties. Composed of advanced rare earth oxides such as neodymium and samarium, C0G (NP0) provides one of the most stable dielectric behaviors available in ceramic technology. Capacitance shift over temperature is minimal—within 0 ± 30 ppm/°C, translating to less than ±0.3% from -55°C to +125°C. This predictability supports designs that cannot tolerate drift or performance uncertainty over ambient changes.

KYOCERA AVX 04025A3R0BAT2A Electrical Characteristics and Reliability

The electrical characteristics of the 04025A3R0BAT2A reflect its high-grade dielectric. Capacitance hysteresis and drift remain below ±0.05%—significantly outperforming alternatives like film capacitors, which can exhibit up to ±2%. Long-term life stability is evident in its less than ±0.1% capacitance change, or one-fifth that of most other dielectric families. The device’s rated voltage of 50 V increases its applicability in both signal processing and low-power DC decoupling roles, ensuring safe margin for transients and input surges commonly encountered in demanding circuits.
