1825AC683MAT3A

The 1825AC683MAT3A is a surface-mount multilayer ceramic capacitor (MLCC) manufactured by Kyocera AVX. It offers a capacitance of 0.068 microfarads (µF) with a tolerance of ±20%. This capacitor is rated for a high operating voltage of 1000V DC (1kV), making it suitable for high-voltage power circuits. The X7R dielectric provides stable capacitance over a temperature range of -55°C to +125°C, with a typical capacitance change of ±15%.

The capacitor is housed in an 1825 (4564 metric) package measuring 4.50mm in length, 6.40mm in width, and a maximum thickness of 2.54mm. It features a surface-mount construction ideal for automated PCB assembly. The component is marked as RoHS3 compliant and REACH unaffected, although these compliance statuses have not been independently verified by the distributor.

This general-purpose MLCC is designed for applications requiring high voltage handling, such as snubber circuits, DC-link filtering, and coupling/decoupling in power supplies. The high voltage rating combined with the compact 1825 footprint allows designers to save board space while meeting stringent voltage requirements. As with all ceramic capacitors, care should be taken with DC bias effects on capacitance, especially at high voltages.
