1812AC103JAT1A

The 1812AC103JAT1A is a high voltage multilayer ceramic capacitor (MLCC) from Kyocera AVX, designed for applications requiring stable capacitance under high voltage conditions. With a capacitance of 10000 pF (0.01 µF) and a rated voltage of 1000V DC, this component is suitable for snubber circuits in high frequency power converters, resonators in switch-mode power supplies (SMPS), and high voltage coupling or DC blocking applications.

The capacitor uses X7R dielectric, providing a capacitance change of ±15% over the operating temperature range of -55°C to 125°C. It offers a tolerance of ±5% and features low equivalent series resistance (ESR) at high frequencies. The component is housed in an 1812 (4532 Metric) surface mount package with dimensions of 4.60mm x 3.20mm x 2.20mm. The termination is plated nickel and tin (Ni/Sn), making it RoHS compliant.

Due to its larger physical size, special handling is recommended during assembly. Reflow soldering is preferred for sizes 1210 and larger, and the temperature gradient should not exceed 4°C per second. A protective surface coating may be required to prevent external arcing in high voltage applications. This capacitor is intended for general purpose use and is not designed for AC line filtering with polarity reversal.
