04025A101JAT4A

The 04025A101JAT4A is a multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX. It offers 100pF capacitance with ±5% tolerance and a rated voltage of 50V DC. The dielectric is C0G (NP0), a Class I ceramic material known for its exceptional temperature stability, with a capacitance change of 0 ±30 ppm/°C over the operating temperature range of -55°C to +125°C. This makes the capacitor suitable for resonant circuits, timing applications, and other designs requiring low drift and high Q. The capacitor features a Q factor of ≥1000 (for capacitance ≥30 pF) and insulation resistance of ≥10,000 MΩ.

The component is housed in a compact 0402 (1005 metric) surface mount package, with dimensions of 1.00mm x 0.50mm x 0.56mm maximum. Termination is plated Nickel/Tin (Ni/Sn), ensuring excellent solderability. It is intended for general-purpose applications and is RoHS compliant (unverified). The part uses tape and reel packaging (13" reel) for automated assembly.

Design engineers should note the dielectric strength of 250% of rated voltage (no breakdown at 125V) and the low capacitance drift over life (<0.1% typical). With a wide operating temperature range and stable characteristics, this capacitor is ideal for high-frequency filtering, bypass, and coupling in industrial, consumer, and automotive electronics where reliability is critical.
