GRM155R61E224KE01D

The GRM155R61E224KE01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for use in a wide range of industrial, consumer, and telecommunications applications where reliable, compact energy storage and filtering are required. Multilayer ceramic capacitors like this model are constructed from multiple layers of ceramic dielectric material interleaved with metal electrodes, all fired together into a single monolithic structure. This construction method allows manufacturers to achieve high capacitance values in very small physical packages. The GRM155R61E224KE01D features a 0402 package size (1.0 x 0.5 millimeters), making it ideal for space-constrained applications and modern surface-mount assembly processes used in compact electronics. This capacitor belongs to Murata's GRM series, which is recognized across the electronics industry for consistent quality and performance in mainstream applications. The part number designation itself encodes key specifications: the "155" refers to the 0402 package, the "61E" indicates the voltage and temperature characteristics, and "224K" describes the capacitance value. Capacitors in this series are commonly used in power supply filtering, signal coupling and decoupling, noise suppression, and timing circuits. Engineers typically specify this particular part when designing circuits that require a balance of performance, reliability, and cost-effectiveness. The 0402 package size is standard across modern PCB designs, ensuring compatibility with contemporary manufacturing equipment and assembly processes. Murata's GRM series has proven itself through extensive deployment in consumer electronics, industrial control systems, automotive applications, and telecommunications infrastructure, making it a trusted choice for both prototype development and high-volume production. Ceramic capacitors are preferred over alternative technologies in many applications due to their excellent frequency response, low equivalent series resistance (ESR), stability across temperature ranges, and long shelf life. The specific characteristics of this part make it suitable for both DC blocking and AC filtering applications, where engineers need predictable performance without the size penalties associated with electrolytic or film capacitor alternatives. For engineers evaluating alternatives, this Murata part offers the advantages of a well-established design with proven field reliability, extensive third-party compatibility data, and availability through multiple distribution channels. The standardized 0402 package ensures straightforward PCB layout and design-in without requiring specialized manufacturing accommodations.
