GRM2165C1H391JA01J

The GRM2165C1H391JA01J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a comprehensive family of general-purpose ceramic capacitors widely used across industrial, automotive, telecommunications, and consumer electronics applications. Multilayer ceramic capacitors like this component serve as fundamental building blocks in modern electronics, functioning to store electrical charge, filter signals, couple and decouple circuits, and stabilize voltage supplies. The GRM2165C1H391JA01J designation contains important encoded information about its electrical and physical characteristics. The "2165" in the part number indicates the component uses a 0805 metric package size (3.2 mm × 1.6 mm), a standard dimension that offers a practical balance between compact board integration and ease of handling during manufacturing and assembly. The "C1H" portion specifies the capacitor's dielectric class and voltage rating, placing it in a temperature-stable category suitable for applications requiring reliable performance across temperature ranges typical in industrial and commercial environments. This particular configuration makes the GRM2165C1H391JA01J suitable for use in power supply circuits, signal conditioning networks, resonant circuits, and general-purpose filtering applications. Engineers commonly specify components from this family in motherboards, industrial control systems, LED drivers, power management modules, and RF/microwave subsystems. The 0805 package size is especially popular in modern design because it accommodates automated pick-and-place assembly, reduces PCB real estate requirements compared to larger packages, and provides sufficient voltage and capacitance ratings for a broad spectrum of applications without unnecessary size overhead. The Murata GRM series' reputation for consistency, reliability, and temperature stability across extended operating ranges makes these capacitors preferred choices in demanding environments where component failure could disrupt critical operations. Industrial buyers and design engineers often select specific part numbers from this series based on their precise combinations of voltage rating, capacitance value, and temperature characteristics, allowing them to optimize circuit performance while maintaining supply chain reliability through an established manufacturer with global distribution. For applications requiring a stable, compact, general-purpose ceramic capacitor with proven field performance, the GRM2165C1H391JA01J offers the dependability expected from Murata's established component platforms.
