GRM155R71C104KA88D

The GRM155R71C104KA88D 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, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions including energy storage, signal filtering, noise suppression, and voltage smoothing in power supply circuits. The GRM series specifically is designed to balance cost-effectiveness with reliable performance, making these components suitable for high-volume production environments where both quality and value are important considerations. The part number structure provides insight into this capacitor's characteristics. The "155" designation indicates the package size classification, corresponding to 0402 metric dimensions (1.0mm × 0.5mm), making it a compact surface-mount device suitable for densely populated circuit boards. This small footprint is particularly valuable in space-constrained applications such as portable consumer devices, compact industrial controllers, and modern IoT equipment where board real estate is at a premium. The ceramic material composition and internal construction of GRM-series capacitors make them suitable for general-purpose filtering and decoupling applications across a wide operating range. These capacitors are commonly found in power distribution networks, where they reduce voltage ripple and suppress high-frequency noise. They're also frequently specified for signal coupling and bypass roles in audio circuits, mixed-signal electronics, and digital logic systems. Engineers typically specify Murata GRM capacitors when they need proven reliability from an established manufacturer combined with broad availability across global distribution channels. The GRM series benefits from extensive characterization data and proven performance history in millions of deployed units. This track record reduces design risk, particularly in applications where component consistency and long-term availability are critical. The 0402 package size of this specific part makes it especially relevant for modern surface-mount manufacturing processes using standard pick-and-place equipment. This compatibility with mainstream assembly techniques ensures that engineers can source replacements easily and maintain consistent production economics throughout a product's lifecycle. For applications requiring specific electrical performance, the GRM series offers numerous variants across different voltage ratings, capacitance values, and temperature coefficients. This allows design engineers to select the exact specification needed without over-specifying and unnecessarily increasing component cost. The standardization within the GRM family also simplifies inventory management for manufacturers and distributors.
