08055A391FAT2A

The 08055A391FAT2A is a surface mount multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX. This component features a capacitance of 390 pF with a tolerance of ±1%, rated voltage of 50V DC, and utilizes a C0G (NP0) Class I dielectric. C0G dielectric offers excellent temperature stability with a capacitance change of less than ±0.3% over the full operating temperature range of -55°C to +125°C, making it suitable for precision timing, filtering, and oscillator circuits.

Electrical characteristics include a minimum Q factor of 1000 at 1 MHz for capacitance values ≥30 pF, a minimum insulation resistance of 10,000 MΩ, and no breakdown during dielectric strength testing at 250% of rated voltage. These parameters ensure reliable performance in high-frequency and low-loss applications.

The capacitor is housed in an industry-standard 0805 (2012 metric) package measuring 2.01mm x 1.25mm with a maximum thickness of 0.94mm. It features a plated nickel and tin termination finish and is supplied on 7-inch reels for automated surface mount assembly. The mounting type is surface mount, suitable for reflow soldering processes.

This component is designed for general purpose applications including DC blocking, bypassing, coupling, and timing circuits where stable capacitance over temperature and voltage is required. The C0G dielectric exhibits negligible capacitance drift and hysteresis, providing long-term reliability.
