18121C225KAT2A

This is a surface mount multilayer ceramic capacitor (MLCC) from Kyocera AVX, part number 18121C225KAT2A. It offers a capacitance of 2.2 µF with a tolerance of ±10% and a rated voltage of 100V. The X7R dielectric provides stable capacitance over a wide temperature range of -55°C to +125°C, with a capacitance change of ±15%.\n\nDesigned for general purpose applications, this capacitor features a 1812 (4532 Metric) package with dimensions of 4.50mm length, 3.20mm width, and a maximum thickness of 2.79mm. The terminations are plated with nickel and tin, suitable for surface mount soldering. It is supplied on 7-inch tape and reel for automated assembly.\n\nThe X7R dielectric is a Class II material, offering high volumetric efficiency. The capacitor meets the dissipation factor limit of ≤10% at 1kHz and insulation resistance of 10,000MΩ or 500MΩ-µF, whichever is less. It can withstand 250% of rated voltage without breakdown.
