1808CA391KAT1A Description

Short technical summary and product information.

The Kyocera AVX 1808CA391KAT1A is a surface-mount multilayer ceramic capacitor (MLCC) with a capacitance of 390 pF and a rated voltage of 630 V. It features a C0G/NP0 temperature coefficient, offering stable capacitance over a wide temperature range from -55°C to 125°C. The tolerance is ±10%.

 

This capacitor is designed for general purpose applications where high voltage capability is required. The 1808 (4520 Metric) package measures 4.60mm x 2.00mm with a maximum thickness of 1.45mm, making it suitable for compact PCB designs. The MLCC construction provides low equivalent series resistance (ESR) and excellent high-frequency performance.

 

With its high voltage rating and stable dielectric, this component is ideal for power supply filtering, snubber circuits, and DC-DC converter applications. The C0G/NP0 dielectric ensures minimal capacitance change with temperature and voltage, making it suitable for timing and coupling circuits.
