## Description

The Kyocera AVX 1808JA390KAT1A is a surface-mount multilayer ceramic capacitor (MLCC) with a capacitance of 39 pF and a rated voltage of 4000V (4kV). It features a ±10% tolerance and a C0G (NP0) temperature coefficient, offering stable capacitance over a wide temperature range from -55°C to 125°C.

This capacitor is designed for general-purpose applications requiring high voltage handling in a compact footprint. The 1808 (4520 metric) package measures 4.60mm x 2.00mm with a maximum thickness of 2.20mm, making it suitable for space-constrained designs.

The high voltage feature enables use in power supplies, inverters, and other circuits where voltage stress is a concern. The NP0 dielectric provides low capacitance drift and low losses, ideal for timing and filtering circuits.
