1812AC223KAT1A Description

Short technical summary and product information.

The Kyocera AVX 1812AC223KAT1A is a high voltage multilayer ceramic capacitor (MLCC) with a capacitance of 0.022 µF and a rated voltage of 1000V (1kV). It features an X7R temperature coefficient, providing stable capacitance over a temperature range of -55°C to 125°C with a tolerance of ±10%. This capacitor is designed for surface mount assembly in an 1812 (4532 Metric) package with plated nickel and tin terminations, making it RoHS compliant.

 

Typical applications include snubber circuits in high frequency power converters, resonators in switch-mode power supplies (SMPS), and high voltage coupling or DC blocking. Due to its larger physical size, reflow soldering is recommended for reliable assembly, and protective surface coating may be required to prevent external arcing in high voltage environments.

 

The component is suitable for general purpose use where high voltage and moderate capacitance are needed. Its X7R dielectric offers good temperature stability and is not intended for AC mains filtering or polarity reversal applications.
