GRM31MR61C564KA01L

The GRM31MR61C564KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and automotive applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuits. They serve critical functions including energy storage, signal filtering, noise suppression, and power distribution. The GRM31 designation indicates this is a surface-mount component in the 1206 package size (3.2mm × 2.5mm), making it suitable for compact PCB designs where space efficiency is important. This standardized package type ensures compatibility with automated assembly processes and allows engineers to work with familiar footprints across multiple designs. The "MR" designation within the part number identifies the dielectric material and temperature characteristics of this capacitor. Murata's MR series capacitors are specified for general industrial and commercial applications, offering reliable performance across typical operating temperature ranges. These capacitors are designed to maintain stable capacitance values across their rated temperature range, making them suitable for applications where thermal stability is important but extreme performance is not required. The numerical portion of the part number encodes the capacitance value and voltage rating. Engineers typically specify MLCCs from the GRM31 family when designing filtering networks, bypass circuits, coupling applications, and energy storage functions in power supplies, audio circuits, RF modules, and digital logic boards. What distinguishes exact part numbers like this one is the combination of capacitance value, voltage rating, and tolerance class—all encoded in the part number itself. Engineers select specific GRM31 variants based on their circuit requirements, PCB layout constraints, and cost considerations. The 1206 package offers a good balance between component size and handling characteristics during manufacturing, and provides adequate surface area for reliable solder joints on modern PCBs. Murata's GRM series has established a strong reputation for consistency and reliability in high-volume manufacturing environments. This makes GRM31MR61C564KA01L a preferred choice for design engineers who need proven, readily available capacitors with predictable performance characteristics. The broad availability of this part number across the global supply chain makes it a practical specification choice for production equipment requiring component longevity and procurement reliability.
