GRM21BC81C226ME44L

# GRM21BC81C226ME44L - Murata Multilayer Ceramic Capacitor The GRM21BC81C226ME44L is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, which represents a broad family of general-purpose ceramic capacitors designed for mainstream industrial and consumer electronics applications. Multilayer ceramic capacitors (MLCCs) are among the most widely used passive components in modern electronics. They provide stable capacitance in a compact form factor, making them essential for filtering, decoupling, timing circuits, and energy storage across countless applications. The GRM21 designation indicates this is a surface-mount device in a compact 0805 package size, measuring approximately 2.0mm x 1.25mm. This small footprint makes it ideal for high-density circuit boards where space is a premium concern, particularly in portable equipment, automotive electronics, industrial control systems, and telecommunications infrastructure. The "BC81" portion of the part number indicates this capacitor uses Murata's standard X7R dielectric material. X7R is known for its temperature stability and reliability across a broad operating temperature range, making it suitable for applications where temperature fluctuations are expected. This dielectric formulation is preferred over Y5V or Z5U alternatives when consistent performance across temperature variations is required, though capacitance variation will still occur over the temperature spectrum. The "C226" segment specifies the capacitance value and tolerance class. Engineers select this specific part when the application requires this exact capacitance specification alongside the X7R dielectric properties. The ME44L suffix indicates Murata's RoHS-compliant construction with lead-free terminations, meeting modern environmental and regulatory standards required for most industrial and consumer markets. Engineers specify the GRM21BC81C226ME44L over alternatives when they need the combination of this capacitance value, X7R temperature stability, compact 0805 package dimensions, and verified reliability from a trusted manufacturer. Murata's GRM series capacitors are recognized for consistent quality and availability, which reduces supply chain risk compared to less established sources. This component is typically found in power supply circuits for digital logic, analog signal processing, impedance matching networks, and as bypass capacitors in high-speed digital systems. Its small size and established performance profile make it a common choice in design specifications across industrial automation, medical equipment, power electronics, and telecommunications applications where proven reliability and compact packaging are essential requirements.
