GRM21BR61A106KE19L

The GRM21BR61A106KE19L is a ceramic multilayer chip capacitor manufactured by Murata, one of the world's leading suppliers of passive electronic components. This surface-mount capacitor belongs to the GRM21 series, which is designed for general-purpose applications across consumer electronics, industrial equipment, and telecommunications infrastructure. Ceramic capacitors like this component are fundamental building blocks in modern electronic circuits, serving critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and voltage stabilization. The GRM21 series is specifically engineered to balance performance, reliability, and cost-effectiveness for mainstream industrial and commercial applications rather than extreme military or aerospace specifications. The part number itself encodes important information about the component's characteristics. The "21" designation refers to the physical package size, indicating a 0805 metric footprint (approximately 2.0mm x 1.25mm), making it suitable for compact circuit board designs while remaining large enough for reliable hand and automated assembly. This package size is widely adopted in industrial electronics where space efficiency matters but components must still be serviceable and repairable. The "BR" and "61A" portions of the designation indicate the dielectric material class and voltage rating. Murata's X7R dielectrics, common in this series, provide stable capacitance across a wide operating temperature range and are preferred for applications where temperature stability is important. This makes the capacitor suitable for industrial environments with fluctuating thermal conditions. Engineers typically specify the GRM21BR61A106KE19L for applications requiring reliable, cost-effective capacitive filtering and energy storage in intermediate voltage circuits. Common uses include input and output filtering on power supplies, transient suppression on digital signal lines, and decoupling in audio and sensor interfaces. The component's proven track record in high-volume manufacturing environments makes it a dependable choice for products requiring consistent performance and long-term availability. Compared to alternatives, this specific part offers a pragmatic combination of proven technology, established supply chains, and performance adequate for the vast majority of general industrial applications. Engineers choosing this component can benefit from extensive application notes, reference designs, and compatibility data available across countless existing installations. For applications demanding exceptional precision, extreme temperature performance, or specialized dielectric properties, alternative capacitor series may be more appropriate. However, for straightforward industrial electronics applications prioritizing reliability and proven performance, the GRM21BR61A106KE19L represents an efficient specification choice.
