GRM21BC71E475KE11L

# GRM21BC71E475KE11L Multilayer Ceramic Capacitor by Murata The GRM21BC71E475KE11L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This part belongs to Murata's GRM series, a family of general-purpose ceramic capacitors designed for mainstream industrial and consumer electronics applications where cost-effectiveness and reliability are essential. Multilayer ceramic capacitors like this unit are among the most widely used passive components in modern electronics. They function to store electrical charge, filter signals, and stabilize voltage supplies across countless circuit designs. The GRM21BC71E475KE11L features a 1206 surface-mount package (also designated as 3216 in metric measurements), making it suitable for automated assembly on printed circuit boards alongside other standard surface-mount components. This package size represents a common middle ground in MLCC sizing, offering adequate capacitance in a compact form factor. The part designation indicates this capacitor operates at a voltage rating in the 6.3V to 16V range typical for general-purpose applications, with a capacitance value suited for decoupling, filtering, and coupling roles in low-to-mid voltage circuits. Engineers commonly specify capacitors from the GRM series in power supply filtering stages, signal coupling networks, and noise suppression applications throughout industrial control systems, consumer electronics, telecommunications equipment, and automotive electronics. Murata's GRM series capacitors are engineered to meet stringent reliability requirements across industrial temperature ranges. They exhibit stable performance characteristics across typical operating conditions, making them a dependable choice for applications where consistent electrical behavior is necessary over extended product lifecycles. The ceramic dielectric material provides good frequency response characteristics and maintains capacitance relatively stable compared to some alternative dielectric formulations. Engineers might select this specific part number based on several considerations: the standardized 1206 package provides easy integration into existing PCB designs and manufacturing processes; Murata's proven track record ensures consistent quality and availability; and the GRM series offers an established performance envelope with predictable behavior in well-understood application circuits. For designers working on cost-sensitive applications requiring proven reliability without specialized performance requirements, the GRM21BC71E475KE11L represents a practical, well-documented choice. The compact surface-mount design, combined with Murata's manufacturing quality, makes this capacitor suitable for high-volume production environments where consistency and ease of assembly are valued alongside component performance.
