GRM21A5C2E270JW01D

The GRM21A5C2E270JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors like this unit function as energy storage and filtering devices in electronic circuits. They are essential for decoupling, bypassing, and signal coupling applications where stable capacitance performance and compact form factor are required. The GRM series is specifically designed for mainstream industrial and commercial applications where cost-effectiveness and reliability must be balanced with performance requirements. The part designation reveals several key characteristics. The package type is 0805 (2.0mm × 1.25mm), which places this among the most widely used surface-mount capacitor sizes in modern electronics manufacturing. This size offers practical benefits: it is small enough for high-density PCB layouts yet large enough to handle standard pick-and-place assembly equipment without requiring specialized handling. The 0805 package also provides reasonable accessibility for rework and repair operations in production and field service environments. Based on the part number structure, this capacitor belongs to the X5R or similar temperature-compensated dielectric class, which is typical for the GRM21A series. Capacitors in this classification maintain relatively stable capacitance across a wide temperature range, making them suitable for applications where thermal stability is important but extreme precision is not critical. This characteristic makes them particularly valuable in power supply circuits, audio equipment, and industrial control systems that must operate reliably under varying environmental conditions. Engineers typically specify Murata's GRM series capacitors when they need reliable, proven components from an established manufacturer with excellent availability and consistent quality. The combination of standard package sizing, proven performance across millions of deployed units, and straightforward sourcing through established distribution channels makes this part a logical choice for both original equipment manufacturers and contract manufacturers building to established designs. The GRM21A5C2E270JW01D represents the kind of fundamental passive component that appears in countless industrial and consumer applications where performance, availability, and predictability are paramount. Designers often standardize on specific Murata MLCC part numbers to simplify procurement, reduce supply chain complexity, and ensure consistent circuit behavior across production runs.
