08055A221GAT4A

This 08055A221GAT4A is a 220 pF surface-mount MLCC (multilayer ceramic capacitor) manufactured by Kyocera AVX. It features a C0G (NP0) dielectric, which is a Class I temperature-compensating ceramic offering excellent stability. Capacitance change with temperature is 0 ±30 ppm/°C, and the operating temperature range is -55°C to +125°C. The capacitor is rated for 50V DC and has a tolerance of ±2%.

The C0G dielectric provides low capacitance drift and hysteresis, making it suitable for applications requiring stable capacitance over time and temperature. Typical applications include timing circuits, filters, and resonant circuits. The high Q factor (minimum 1000 for capacitance ≥30 pF) ensures low losses.

The component is housed in an 0805 (2012 Metric) package with dimensions 2.01mm x 1.25mm x 0.94mm (max). It is designed for surface mount technology (SMT) and uses a plated nickel and tin termination finish. The capacitor is supplied in 7-inch reel packaging for automated assembly.

Dielectric strength is tested at 125V (250% of rated voltage) with no breakdown, and insulation resistance is a minimum of 10,000 MΩ. These characteristics ensure reliability in high-impedance circuits.
