GRM21BR61H475KE51L

The GRM21BR61H475KE51L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, which represents a broad family of general-purpose MLCCs designed for diverse industrial and consumer applications. Multilayer ceramic capacitors are fundamental passive components used to store electrical charge and filter signals in electronic circuits. They appear in virtually every modern electronic device, from consumer electronics to industrial control systems, telecommunications equipment, and automotive applications. The GRM series specifically targets applications where reliable performance and cost-effectiveness are balanced with reasonable electrical specifications. The part number itself encodes important information about this specific capacitor's characteristics. The "21" in the designation indicates the physical package size, identifying this as a 2012-case component—a compact surface-mount format measuring 2.0mm by 1.25mm. This small footprint makes it ideal for space-constrained applications and high-density circuit board designs where miniaturization is important. The capacitor is designed for automatic pick-and-place assembly on PCBs, streamlining manufacturing processes. The GRM21BR series utilizes standard dielectric materials and construction techniques that position these capacitors in the commercial-grade performance category. They are well-suited for general-purpose filtering, decoupling, and signal coupling applications throughout industrial electronics, power supplies, instrumentation, and embedded systems. Engineers select MLCCs like this when they need reliable charge storage and frequency filtering without requiring exotic materials or extreme performance specifications. What distinguishes this particular part number from alternatives in the GRM family is its specific electrical rating combination. The unique alphanumeric suffix identifies distinct voltage and capacitance values. Engineers specify this exact part when their circuit design requires the particular electrical characteristics encoded in this designation—whether matching a specific decoupling strategy, impedance requirement, or other circuit parameter. Using the correct part number ensures the component meets design specifications without over-specification that increases cost or under-specification that compromises circuit performance. Murata's GRM series capacitors are manufactured to strict quality standards and are widely used by OEMs and contract manufacturers globally. The standardized part numbering system, broad availability, and proven reliability make these components a practical choice for engineers designing everything from simple filter circuits to complex industrial control systems. Designers often stock multiple GRM series variants to cover different voltage and capacitance requirements across various product lines.
