GRM21BR71E184KA01L

The GRM21BR71E184KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, a widely-used family of surface-mount ceramic capacitors designed for high-reliability applications in industrial, consumer, and telecommunications equipment. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling across virtually every type of circuit board. The GRM series is particularly known for consistent performance, compact form factors, and cost-effectiveness in high-volume production environments. The part number structure indicates this capacitor uses a 0805 package size (2.0mm × 1.25mm), making it suitable for standard surface-mount assembly processes. This package size strikes a practical balance between board real estate conservation and handling ease during manufacturing, making it popular in space-constrained industrial designs while remaining straightforward to place and solder with automated equipment. Murata's GRM ceramic capacitors are specified across industries including automotive electronics, industrial control systems, power supplies, LED lighting drivers, medical devices, and communication infrastructure. Engineers select these components for applications requiring stable capacitance over temperature ranges, low equivalent series resistance (ESR), and proven reliability in demanding environments. The ceramic dielectric material provides excellent frequency response characteristics, making these capacitors equally suitable for DC filtering and AC coupling applications. The series designation "BR" within the part number indicates this capacitor belongs to a specific performance classification within Murata's product portfolio. These capacitors are engineered to maintain predictable electrical behavior across their intended operating range, with attention paid to aging characteristics and reliability metrics important for long-life industrial equipment. Designers commonly specify Murata GRM-series capacitors when they require a trusted, readily-available component with established field history. The combination of widespread availability, consistent quality, and compatibility with standard manufacturing processes makes this part number a practical choice for engineers developing equipment that must meet reliability requirements without introducing supply chain risk. Whether used in bulk capacitor networks across a motherboard, as part of precision filtering in a sensor interface, or within power conversion circuits, the GRM21BR71E184KA01L represents the type of foundational passive component that enables reliable operation of industrial electronic systems.
