GRM21BR61E225KA12L

The GRM21BR61E225KA12L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's largest producers of passive electronic components. This capacitor is designed for general-purpose filtering, decoupling, and signal coupling applications across a broad range of industrial and consumer electronics equipment. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The GRM21BR61E225KA12L belongs to Murata's GRM series, which is engineered to deliver stable performance across temperature ranges and frequency spans commonly encountered in industrial control systems, power management circuits, telecommunications equipment, and automotive electronics. The part number itself encodes key information about the component. The GRM21 designation indicates a 0805-inch package size (2.0mm × 1.25mm), which is a standard surface-mount format that balances ease of handling with space efficiency on modern printed circuit boards. This package size is ideal for applications where board real estate is constrained but component accessibility and solderability remain important. The BR and E codes reference the capacitor's dielectric material formulation and voltage rating, indicating this is a Class II ceramic capacitor optimized for mid-range voltage applications rather than extreme high-voltage or high-stability specifications. Engineers typically specify this particular part when they need a reliable, off-the-shelf capacitor for non-critical filtering and decoupling roles where exact capacitance tolerance and temperature stability are less stringent than specialized applications demand. The GRM21BR61E225KA12L fills a practical middle ground in the MLCC landscape—it offers better performance than the most economy-grade alternatives while avoiding the higher cost of precision or high-temperature-rated capacitors in applications that don't require them. This capacitor is commonly found in power supply bypass networks, EMI filtering circuits, AC coupling stages, and general-purpose decoupling applications throughout industrial equipment. Its small footprint makes it particularly valuable in densely populated circuit boards where space optimization is critical, yet its proven reliability in the GRM family makes it a low-risk choice for design engineers who have successfully used similar Murata ceramics in previous projects. The robust supply chain and widespread availability of GRM series capacitors also make this part an attractive specification choice for manufacturers concerned with long-term sourcing reliability and consistent component quality across production runs.
