1808SC391KAT1A Description

Short technical summary and product information.

The 1808SC391KAT1A from Kyocera AVX is a high-voltage ceramic capacitor designed for general purpose applications. It offers a capacitance of 390 pF with a tolerance of ±10% and a rated voltage of 1500V (1.5kV). The X7R temperature coefficient provides stable performance over -55°C to 125°C, making it suitable for a wide range of environments.

 

This MLCC (multilayer ceramic capacitor) features a surface mount design in the compact 1808 (4520 Metric) case size. With dimensions of 4.60mm length, 2.00mm width, and 1.80mm maximum thickness, it fits into space-constrained PCB layouts. The component is RoHS3 compliant and REACH unaffected, meeting current environmental regulations.

 

Designed for high voltage applications, this capacitor can be used in power supplies, snubber circuits, and filtering where reliable performance under high stress is required. The X7R dielectric offers good capacitance stability over temperature and voltage variation.
