GRM21B7U2E272JW32L

# Product Description The GRM21B7U2E272JW32L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of surface-mount ceramic capacitors designed for reliability and performance across demanding industrial and consumer applications. Multilayer ceramic capacitors like this part function as energy storage and filtering elements in electronic circuits. They are used to smooth voltage ripple, decouple power supplies, filter high-frequency noise, and stabilize signal integrity in digital and analog circuits. The compact surface-mount design allows for dense PCB layouts and automated assembly processes, making MLCCs the most widely adopted capacitor technology in modern electronics manufacturing. The GRM21B7U2E272JW32L features a 0805 imperial package size (approximately 2.0mm × 1.25mm), which represents the standard mid-range footprint for general-purpose applications. This size balances component density with handling and placement ease, making it popular in consumer electronics, industrial control systems, telecommunications equipment, and automotive electronics. The 0805 package is also highly compatible with standard pick-and-place equipment and standard PCB design tools. Based on its part number designation, this capacitor carries a rated voltage of 25V, making it suitable for typical 3.3V, 5V, and 12V circuit applications with appropriate safety margins. The capacitance value is 2700pF (0.0027µF), which places it in the range typically used for high-frequency filtering, bypass applications, and EMI suppression rather than bulk energy storage. This value is particularly useful for decoupling integrated circuits, filtering clock signals, and stabilizing radio frequency or high-speed digital circuits. Murata's GRM series capacitors are manufactured with advanced dielectric formulations and construction techniques that provide stable performance across temperature ranges typical for industrial and commercial equipment. The series is recognized for consistent electrical characteristics, low equivalent series resistance (ESR), and reliability in high-reliability applications. Engineers specify this exact part when they require a proven, mainstream component with well-documented performance, broad availability, and proven field history in established applications. The combination of package size, voltage rating, and capacitance value makes this part suitable for engineers designing compact power delivery networks, signal integrity filtering, or EMI control in industrial or commercial electronics where proven technology and supply chain stability are important considerations.
