1808HA101JAT1A

The Kyocera AVX 1808HA101JAT1A is a high voltage multilayer ceramic chip capacitor (MLCC) with a capacitance of 100 pF and a rated voltage of 3000V (3kV). It features a C0G/NP0 temperature coefficient, providing stable capacitance over a wide temperature range from -55°C to 125°C. The capacitor has a tolerance of ±5% and is designed for general purpose applications requiring high voltage handling.

This component is housed in an 1808 (4520 Metric) surface mount package with dimensions of 4.60mm length, 2.00mm width, and a maximum thickness of 2.20mm. The terminations are plated with nickel and tin, making it RoHS compliant. The part is suitable for reflow soldering and is intended for use in high voltage circuits such as snubbers in power converters, resonators in switch-mode power supplies, and DC blocking applications.

As a high voltage MLCC, it exhibits low equivalent series resistance (ESR) at high frequencies, making it effective in high frequency power conversion and filtering circuits. The larger physical size (1808) is necessary to achieve the high voltage rating. Care should be taken during assembly to control temperature gradients and preheat conditions to avoid thermal shock.
