GRM31MR71E105KA01K Description

Short technical summary and product information.

The Murata GRM31MR71E105KA01K is a multilayer ceramic capacitor (MLCC) with a nominal capacitance of 1 µF and a rated voltage of 25V DC. It features an X7R temperature coefficient, which provides a capacitance change of ±15% over the operating temperature range of -55°C to 125°C. This capacitor is designed for general purpose applications and is housed in a standard 1206 (3216 Metric) surface mount package.

 

With a capacitance tolerance of ±10%, this component ensures reliable performance in decoupling, filtering, and bypass circuits. The dissipation factor is limited to 0.025 at rated voltage, and the insulation resistance exceeds 500 Ω·F after a 2-minute charge. The physical dimensions are 3.2 mm length, 1.6 mm width, and a maximum thickness of 1.25 mm, making it suitable for compact PCB layouts.

 

The capacitor is supplied in tape and reel packaging, with standard quantities of 3000 pieces per 180mm reel or 10000 pieces per 330mm reel. It is RoHS3 compliant and has an MSL rating of 1 (unlimited floor life). Note that compliance status is unverified and should be confirmed with the manufacturer.
