概述

Description

GRM31CR72A225KA73L is a Murata MLCC (multilayer ceramic capacitor) in the GRM31C series. It is a surface-mount capacitor used for decoupling and filtering in power/analog circuits.
Key points:
- Capacitance: 2.2 µF (code 225 = 22 × 10^5 pF)
- Dielectric: X7R (indicated by the R72 portion of the code)
- Tolerance: ±10% (K)
- Size: ~3.1 × 2.5 mm (GRM31 family)
- Voltage rating and exact terminations: not fully specified by the code here; consult the datasheet for the precise voltage rating and lead finish.
In short, it’s a 2.2 µF, X7R, 3.1×2.5 mm MLCC used for compact, stable capacitance in electronic circuits. For exact voltage rating, batch/date information, and suitability, refer to Murata’s datasheet.
