## Description

The Kyocera AVX 08055A391JAT2A is a surface mount multilayer ceramic capacitor (MLCC) with a capacitance of 390 pF and a rated voltage of 50V. It uses a C0G (NP0) dielectric, which is a Class I ceramic material offering excellent temperature stability with a capacitance change of 0 ±30 ppm/°C over the operating temperature range of -55°C to +125°C.

This capacitor is housed in an 0805 (2012 Metric) package measuring 2.01 mm x 1.25 mm with a maximum thickness of 0.94 mm. It features plated nickel and tin terminations and is designed for general purpose applications. The part has a quality factor of at least 1000 at 1 MHz and 1 Vrms, and an insulation resistance of 10,000 MΩ or 500 MΩ-µF whichever is less.

The C0G dielectric provides negligible capacitance drift and hysteresis, making this capacitor suitable for timing, filtering, and resonant circuit applications where stability is critical. The part is RoHS3 compliant and has an MSL of 1 (unlimited).
