GRM31M5C1H473JA01L

The GRM31M5C1H473JA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to Murata's GRM series, which is widely recognized across industrial and consumer electronics applications for reliable performance and consistent quality. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling across virtually every type of circuit board. The GRM31 designation indicates this is a surface-mount component in the 1206 package size (approximately 3.2mm × 2.5mm), making it suitable for both standard and space-constrained board layouts. The compact footprint allows designers to maintain flexibility in PCB design while benefiting from proven MLCC technology. The part number's construction reveals key specifications: the "M5C" portion indicates this capacitor uses Class II dielectric material, which provides higher capacitance density compared to Class I ceramics. This makes it particularly valuable in applications where space is limited and moderate capacitance values are required. Class II MLCCs from Murata's GRM series are engineered to balance performance across temperature variations and voltage conditions, though capacitance values will shift somewhat across operating temperature ranges—a characteristic inherent to ceramic dielectrics that experienced engineers account for during circuit design. GRM31M5C MLCCs are commonly found in power distribution networks, where they serve as bypass and decoupling capacitors near integrated circuits to suppress voltage transients and reduce noise. They also appear in analog signal conditioning circuits, audio equipment, industrial control systems, telecommunications infrastructure, and automotive electronics. The broad applicability of this series reflects its versatility across DC and AC applications operating at moderate to higher frequencies. Engineers typically specify Murata's GRM series when they need a balance of cost-effectiveness, reliability, and consistent electrical performance. Murata's manufacturing reputation ensures tight tolerances and low defect rates, which is critical for mission-critical industrial applications where component failure can result in costly downtime. The GRM31M5C1H473JA01L specifically represents a proven solution for applications requiring stable performance within standard commercial operating conditions. When selecting this exact part, engineers benefit from its extensive use history, broad availability in the supply chain, and Murata's long-term commitment to backward compatibility within the GRM family. For applications demanding ceramic capacitor technology in a 1206 package at moderate voltage ratings, this part offers a dependable, well-established choice.
