GRM32RR61E475KA12K

The GRM32RR61E475KA12K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This part represents the GRM series of general-purpose ceramic capacitors, which are among the most widely used capacitors in modern electronics due to their small size, reliability, and cost-effectiveness. Multilayer ceramic capacitors like this one are constructed from alternating layers of ceramic dielectric material and metallic electrodes, all fired together into a compact package. The GRM32 designation indicates this capacitor uses a 1210 metric package size (approximately 3.2mm × 2.5mm), making it suitable for space-constrained applications while still providing substantial capacitive value. The compact footprint allows engineers to achieve higher component density on printed circuit boards without sacrificing performance. This capacitor is specified with Class II dielectric material, which is indicated by the "RR" code in the part number. Class II ceramics offer higher capacitance density compared to Class I alternatives, meaning engineers can achieve larger capacitive values in smaller packages. This characteristic makes Class II MLLCs particularly valuable in decoupling, filtering, and energy storage applications where board space is at a premium. The GRM32RR61E475KA12K is commonly found in power supply circuits, audio equipment, industrial control systems, consumer electronics, telecommunications hardware, and automotive applications. Typical uses include input/output filtering on voltage regulators, power distribution decoupling near integrated circuits, signal coupling and blocking applications, and energy buffering in switched-mode power supplies. Engineers frequently specify Murata's GRM series MLLCs because of their established reliability track record, consistent quality across production batches, and availability through multiple global distribution channels. An engineer might select this specific part number over alternatives due to the combination of package size, voltage rating appropriate for their application, capacitance value, and temperature stability characteristics inherent to the GRM series. Murata MLLCs are known for maintaining stable performance across temperature ranges typical in industrial and commercial environments, making them suitable for applications requiring consistent operation from cold startup to elevated operating temperatures. The RoHS compliance and lead-free construction of modern GRM series capacitors also make them suitable for applications subject to environmental regulations, which is increasingly important in industrial manufacturing and consumer electronics.
