GRM216D71C105KA12D

# Murata GRM216D71C105KA12D Ceramic Capacitor The GRM216D71C105KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Ceramic capacitors in this series are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, allowing them to achieve reasonable capacitance values in a very small physical footprint. The GRM designation indicates this is a commercial-grade component suitable for mainstream industrial and consumer applications where cost-effectiveness and reliability are balanced priorities. The part number structure reveals this capacitor uses a 0805 package size (approximately 2.0mm × 1.25mm in surface-mount format), making it compatible with standard printed circuit board assembly processes. This compact size is one reason engineers select this series—the 0805 package allows for high component density on modern PCBs without requiring specialized equipment or processes. The capacitor is designed for reflow soldering onto FR-4 and similar substrate materials. Murata's GRM series capacitors are typically specified in decoupling and filtering applications, where they suppress voltage ripple, reduce noise on power distribution networks, and stabilize supply voltages to integrated circuits. They are also commonly used in signal coupling, AC filtering, and impedance matching circuits. Engineers often place multiple capacitors of this type in parallel at IC power pins to handle high-frequency noise rejection effectively. The GRM216D series is designed to operate across a wide temperature range suitable for commercial and some industrial environments. These capacitors have relatively stable capacitance characteristics across their rated operating window, though ceramic dielectrics do exhibit some capacitance variation with applied voltage—a consideration engineers account for when specifying ceramic capacitors in precision analog circuits. Engineers select the GRM216D71C105KA12D specifically because it combines Murata's proven reliability with the practical benefits of small package size, standard surface-mount compatibility, and competitive availability. The part is suitable for applications where standard commercial-grade performance meets requirements, though designers working with stringent reliability or temperature specifications may opt for higher-grade alternatives from Murata's portfolio. This capacitor represents the type of foundational passive component essential to nearly all modern electronic assemblies, from power management circuits to high-speed digital signal integrity applications.
