1808AC391KAT1A Description

Short technical summary and product information.

The Kyocera AVX 1808AC391KAT1A is a surface-mount multilayer ceramic capacitor (MLCC) with a nominal capacitance of 390 pF and a tolerance of ±10%. It is rated for a high voltage of 1000V (1kV) and uses an X7R temperature coefficient, ensuring stable performance over an operating temperature range of -55°C to 125°C.

 

This capacitor is designed for general-purpose applications and features a high-voltage design. It is housed in an 1808 (4520 Metric) package with dimensions of 4.60mm length, 2.00mm width, and a maximum thickness of 1.80mm. The surface-mount configuration supports automated assembly processes.

 

The X7R dielectric provides a capacitance change of ±15% over the temperature range, making it suitable for bypass, coupling, and decoupling circuits where moderate stability is required. The high voltage rating allows use in power supply and filtering circuits operating at elevated voltages.
