18121C394MAT2A Description

Short technical summary and product information.

The Kyocera AVX 18121C394MAT2A is a surface-mount multilayer ceramic capacitor (MLCC) with a capacitance of 0.39 µF and a rated voltage of 100V. It uses an X7R temperature coefficient, which provides a capacitance change of ±15% over the operating temperature range of -55°C to 125°C.

 

This capacitor is housed in a standard 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 is RoHS3 compliant.

 

The ±20% tolerance allows for a wide range of acceptable capacitance values, making it suitable for decoupling, filtering, and bypass applications where precise capacitance is not critical.
