GRM2165C1H242JA01D

The GRM2165C1H242JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to Murata's GRM series, which is widely used in consumer electronics, industrial equipment, automotive applications, and telecommunications infrastructure. Multilayer ceramic capacitors are among the most commonly specified passive components in modern electronics due to their small size, reliability, and cost-effectiveness. The GRM2165 designation indicates this part uses a 0805 surface-mount package (2.0mm × 1.25mm), a standard size that balances component density with ease of assembly and rework on printed circuit boards. This package size makes it suitable for applications where board space is constrained but performance requirements are significant. The "1H" designation in the part number indicates this capacitor is rated for 50 volts, making it appropriate for single-supply and dual-supply applications commonly found in industrial control systems, power management circuits, and signal conditioning electronics. The "242" code specifies a capacitance value of 2.4 nanofarads with defined tolerance. This capacitance range is typical for coupling, decoupling, and filtering applications in mid-range frequency circuits. Murata's GRM series capacitors are recognized for consistent performance across temperature ranges and frequency responses, which is critical for industrial and automotive applications where reliability and predictability are essential. These capacitors feature the X7R dielectric, a common choice in industrial applications that provides stable capacitance across operating temperature ranges while maintaining low equivalent series resistance (ESR) and low dissipation factor characteristics. Engineers typically specify this exact part when they need a combination of compact size, proven reliability from an established manufacturer, and stable electrical performance in demanding environments. The 0805 package offers advantages over both smaller packages (which can be difficult to handle and rework) and larger packages (which consume unnecessary board space). The specific voltage and capacitance rating make it particularly suited for decoupling power supply pins on microcontrollers, filtering reference signals in analog circuits, and coupling audio or signal paths in industrial equipment. The GRM2165 series from Murata is qualified for automotive-grade requirements in many configurations, making these parts suitable not only for consumer and general industrial applications but also for the more stringent reliability demands of transportation and safety-critical systems. This broad acceptance across multiple industries, combined with Murata's manufacturing consistency, makes this capacitor a preferred choice when component obsolescence risk and supply chain stability are important considerations for long-term product support.
