## Description

The 18121C105MAT2A is a surface mount multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX. It offers a capacitance of 1 µF with a rated voltage of 100V. The capacitor uses X7R temperature coefficient material, providing stable capacitance over a wide temperature range of -55°C to 125°C. The tolerance is ±20%.

This component is housed in an 1812 (4532 Metric) package with dimensions of 4.57mm length, 3.20mm width, and a maximum thickness of 1.02mm. It is designed for general purpose applications and features surface mount termination suitable for automated assembly processes.

The X7R dielectric makes this capacitor suitable for bypass, coupling, and decoupling applications where moderate capacitance stability is required across temperature variations. The 100V rating allows use in circuits with higher voltage rails.
