GRM21BR61E226ME44K

The GRM21BR61E226ME44K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, which is widely recognized in the electronics industry for reliability and consistency across demanding applications. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronic circuits. They function as energy storage devices, signal filtering elements, and voltage stabilization components in power supplies, amplifiers, and signal processing circuits. The compact form factor and stable electrical characteristics make MLCCs indispensable in applications ranging from consumer electronics to industrial control systems and telecommunications equipment. The part number itself encodes important information about the component. The "21" in the prefix indicates a 0805 metric package size (1.25mm x 2.00mm), a standard surface-mount format that balances board space efficiency with handling ease during assembly. This size is ideal for high-density circuit boards where space is constrained but component reliability cannot be compromised. The package is compatible with standard pick-and-place assembly equipment and wave or reflow soldering processes. The "BR" designation indicates this is a Class II dielectric ceramic capacitor, which offers relatively high capacitance density compared to Class I alternatives. Class II capacitors are commonly specified when moderate voltage and capacitance values are needed with acceptable but non-critical tolerance and temperature stability characteristics. Engineers typically specify the GRM21BR61E226ME44K when their design requires a combination of compact size, proven reliability, and cost-effectiveness. The Murata GRM series is trusted across industrial sectors due to its consistent performance, long-term availability, and extensive qualification history in production environments. This particular variant is commonly found in power management circuits, where it provides filtering and energy buffering functions, as well as in signal conditioning stages of measurement and control systems. The specific part number designation ensures designers receive the exact dielectric formulation, voltage rating, and capacitance value needed for their circuit requirements. Substituting with alternative capacitors from different manufacturers or even different variants within the GRM series could affect circuit performance and reliability. For applications requiring high-reliability components with established supply chains and proven field performance, this Murata MLCC represents a well-established choice in industrial electronics design.
