GRM31A7U3D680JW31D Description

Short technical summary and product information.

The Murata GRM31A7U3D680JW31D is a surface mount multilayer ceramic capacitor (MLCC) with a capacitance of 68 pF, tolerance of ±5%, and a rated voltage of 2000V DC. It uses a U2J dielectric, which offers a stable temperature coefficient of -750±120 ppm/°C from 25°C to 125°C.

Electrically, this capacitor features a minimum Q factor of 1000, ensuring low losses in high-frequency applications. Insulation resistance is at least 10000 MΩ, and the dielectric strength is tested at 200% of the rated voltage. The operating temperature range spans -55°C to 125°C.

The component is housed in a standard 1206 (3216 Metric) package with dimensions 3.2mm x 1.6mm x 1.0mm. It is designed for surface mount assembly and is supplied in tape and reel packaging with 4000 pieces per 180mm reel.

Typical applications include general purpose high voltage circuits, DC-DC converter output filtering, snubber circuits, and coupling/bypass functions where stable capacitance and high voltage rating are required.
