1812AC273KAT1A

Kyocera AVX 1812AC273KAT1A is a high voltage multilayer ceramic capacitor (MLCC) from the company's specialized high voltage MLC chip series, designed for 600V to 5000V applications. This capacitor offers a capacitance of 0.027 µF with a voltage rating of 1000V (1kV) and a tolerance of ±10%. It uses X7R dielectric, which provides a temperature coefficient of ±15% over the full operating temperature range of -55°C to 125°C.

The component is packaged in a standard 1812 (4532 Metric) surface mount package, measuring 4.60mm in length, 3.20mm in width, and 2.80mm in maximum thickness. The termination finish is plated nickel and tin (Ni/Sn), which is RoHS compliant. With an MSL rating of 1 (unlimited), it requires no special moisture sensitivity precautions.

These high voltage MLCCs exhibit low equivalent series resistance (ESR) at high frequencies, making them ideal for use in snubber circuits for high frequency power converters, resonators in switch mode power supplies (SMPS), and high voltage coupling/DC blocking applications. When assembling, reflow soldering is recommended for 1812 size capacitors, and the temperature gradient during soldering should not exceed 4°C per second to prevent thermal shock.
