GRM21BR71H474KA88K

The GRM21BR71H474KA88K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to the GRM series, which represents Murata's general-purpose MLCC line widely used across industrial, consumer, and automotive applications. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions in filtering, decoupling, timing circuits, and signal coupling applications. The GRM series is specifically designed for applications requiring reliable performance in compact form factors while maintaining cost-effectiveness for high-volume production environments. The part number structure indicates this capacitor features a 1206 package size (imperial designation), which measures approximately 3.2mm by 1.6mm. This size strikes a practical balance between miniaturization and ease of handling during assembly, making it suitable for both manual prototyping and automated manufacturing lines. The 1206 package remains one of the most widely adopted sizes for general-purpose applications because it offers adequate capacitance density without requiring specialized soldering equipment. The "BR" designation in the part number indicates this capacitor uses Murata's standard dielectric material formulation optimized for general-purpose use. The "H" rating refers to the voltage class, which positions this component in a mid-range voltage category suitable for consumer and light industrial applications. The "K" tolerance specification indicates standard manufacturing tolerances appropriate for non-critical filtering and coupling applications where exact capacitance values are less critical than in precision timing or frequency-dependent circuits. Engineers typically specify MLCCs from the GRM series when designing power supply filtering stages, EMI suppression networks, signal integrity applications, and general-purpose decoupling near integrated circuits. The combination of small size, reliable performance, and widespread availability makes this part suitable for space-constrained designs where reliability is important but extreme performance specifications are not required. The Murata GRM series has established a strong reputation for consistency and long-term availability, which makes it an attractive choice for designs intended for extended production runs or long-term support requirements. Designers working on industrial control systems, telecommunications equipment, consumer electronics, and automotive subsystems frequently incorporate MLCCs from this series due to their proven track record and compatibility with standard PCB assembly processes. This capacitor is typically selected as part of a broader passive component strategy rather than as a sole solution, often used alongside other capacitors of different values and types to achieve optimal filtering characteristics across the frequency spectrum in power distribution and signal conditioning circuits.
