GRM31MR71A225KA01L

The GRM31MR71A225KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading capacitor suppliers. This component belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic device. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and frequency compensation in circuits. The GRM series is designed for applications requiring reliable, cost-effective capacitance in compact form factors. The "31" in the part number indicates this capacitor uses a 1206 package size (3.2mm × 2.5mm × 2.5mm), making it a surface-mount component suitable for automated PCB assembly. This mid-range package size offers a practical balance between capacitance density and ease of handling, making it popular in both high-volume consumer products and specialized industrial designs. The 1206 package remains one of the most versatile and widely supported package sizes in the industry. The "MR" designation within Murata's naming convention identifies this capacitor as part of their standard temperature-compensated ceramic dielectric series. These capacitors are engineered to maintain stable performance across typical operating temperature ranges, making them suitable for general industrial and commercial applications where moderate temperature stability is required. The "225" in the part number indicates a capacitance value of 2.2 microfarads. At this capacitance level, the GRM31MR series is commonly specified for power delivery networks, bypass applications near integrated circuits, and filtering in audio and analog signal paths. Engineers select this particular value when they need moderate capacitance without resorting to larger packages or electrolytic alternatives. Engineers might specify the GRM31MR71A225KA01L over competing alternatives for several reasons. Murata's reputation for consistent quality and reliability makes their MLCCs a safe choice for mission-critical applications. The 1206 package provides excellent component availability and compatibility with standard manufacturing processes. Additionally, Murata MLCCs typically offer low equivalent series resistance (ESR) and inductance (ESL), important characteristics for effective high-frequency decoupling and noise filtering. This capacitor would typically appear in equipment requiring compact, reliable energy storage and filtering, including industrial power supplies, measurement instruments, networking equipment, and motor control systems. Its standard packaging and proven performance make it a dependable choice for engineers designing products that demand long-term reliability and consistent electrical characteristics.
