GRM155C81E224KE01D

The GRM155C81E224KE01D is a ceramic multilayer chip capacitor manufactured by Murata, one of the world's leading suppliers of passive electronic components. This surface-mount capacitor is housed in a compact 0402 package, making it suitable for space-constrained applications where board real estate is at a premium. Ceramic chip capacitors like this component are fundamental building blocks in modern electronics, used to filter, couple, and decouple signals across countless applications. The 0402 form factor is among the smallest standard package sizes in use today, allowing designers to achieve high component density on printed circuit boards while maintaining manufacturability through standard pick-and-place assembly processes. Murata's GRM series capacitors are widely recognized in the electronics industry for their reliability and consistent performance across commercial and industrial temperature ranges. These components are constructed using advanced ceramic dielectric materials that provide stable capacitance values under varying operating conditions, making them suitable for applications requiring predictable electrical behavior over extended service life. The "E" designation in this part number indicates the component is part of Murata's standard commercial-grade offering, appropriate for general industrial electronics, consumer devices, telecommunications equipment, and automotive applications where cost-effectiveness meets reasonable performance requirements. The component is lead-free and RoHS compliant, reflecting modern environmental and regulatory standards. Engineers typically specify capacitors in this family for bypass and decoupling functions near power supply pins on integrated circuits, where they suppress high-frequency noise and stabilize voltage rails. Their small size and proven reliability make them popular choices in power management circuits, signal conditioning networks, and RF applications. The ceramic construction provides excellent frequency response characteristics, making these capacitors particularly effective at filtering unwanted high-frequency components. When selecting between alternative capacitors, engineers consider factors including package size, dielectric characteristics, voltage rating, temperature stability, and sourcing reliability. The GRM155 series offers an established, cost-effective solution with broad market acceptance and consistent availability through distribution channels. For applications requiring the specific electrical characteristics encoded in this part number's designation, this Murata component provides a proven, standardized choice that simplifies procurement, design verification, and long-term supply chain management.
