GRM31CR71H105KA61L

# GRM31CR71H105KA61L - Murata Multilayer Ceramic Capacitor The GRM31CR71H105KA61L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors designed for reliable performance across diverse industrial and commercial applications. Multilayer ceramic capacitors function as energy storage and filtering devices in electronic circuits. They work by accumulating and releasing electrical charge across ceramic dielectric material sandwiched between metal electrodes. The GRM31CR71H105KA61L employs Murata's proven multilayer construction technique, which stacks numerous thin ceramic layers to achieve stable capacitance in a compact form factor. This design approach enables high volumetric efficiency, making the capacitor suitable for space-constrained applications where component density matters. The part designation itself encodes important specifications. The "GRM31" prefix indicates a 1206 package size (3.2 mm × 2.5 mm), a standard footprint widely used in surface-mount assemblies. This size represents a practical middle ground—larger than 0402 or 0603 packages but smaller than bulkier 1210 or 1812 options—making it suitable for moderate-capacity filtering needs in industrial electronics, power supplies, medical devices, automotive control modules, telecommunications equipment, and consumer electronics. The "71" designation reflects the capacitor's temperature coefficient rating, indicating stable performance across a defined operating temperature range typical of industrial environments. Murata's GRM series capacitors are recognized for their durability, low equivalent series resistance (ESR), and minimal dielectric absorption, making them appropriate for applications requiring reliable DC and AC filtering, decoupling near integrated circuits, and noise suppression in signal paths. Engineers typically specify the GRM31CR71H105KA61L when they require a balanced solution combining proven reliability, standardized packaging that works with existing manufacturing processes, and performance characteristics suitable for industrial-grade electronics. The 1206 package offers better high-frequency performance and lower parasitic effects compared to larger packages while providing more design margin than tiny 0402 components. This capacitor works particularly well in applications where component replacement during manufacturing or field service is occasionally necessary, as its size simplifies handling and rework compared to smaller alternatives. The MURATA manufacturing pedigree ensures consistent quality control, predictable long-term availability, and compatibility with established supply chains across industrial sectors. This part represents a solid engineering choice for applications requiring dependable passive filtering and energy storage in standard surface-mount configurations.
