GRM2165C2A431JA01D

The GRM2165C2A431JA01D 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 recognized in the electronics industry for reliability and consistent performance across demanding applications. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic device. They function to store electrical charge, filter noise, couple signals, and stabilize voltage in circuits. The GRM series specifically is designed to meet the stringent requirements of industrial, automotive, telecommunications, and consumer electronics applications where performance consistency and long-term reliability are critical. Based on its part number designation, this component features a 1206 package size (imperial 0.126 x 0.063 inches), which is a standard surface-mount format widely used in modern PCB assembly. The 1206 package provides a good balance between compact size and ease of handling during manufacturing, making it suitable for high-volume production environments. The "C2A" designation indicates this capacitor is rated for standard industrial voltage classes, while the "431J" specification relates to the capacitance value and tolerance class within Murata's GRM portfolio. Engineers and procurement specialists specify this exact part number for several reasons. First, Murata's GRM series MLCCs are known for stable capacitance across temperature ranges and operating conditions, which is essential for applications where circuit performance cannot drift significantly. Second, these capacitors feature low equivalent series resistance (ESR) and equivalent series inductance (ESL), making them suitable for high-frequency filtering and bypass applications. Third, the proven track record of the GRM series in industrial applications means designers can rely on consistent availability and well-documented performance characteristics. Common application areas for Murata GRM series capacitors include power supply filtering, signal coupling and decoupling in amplifier circuits, frequency compensation in feedback networks, and noise suppression in digital and analog signal paths. They are frequently found in automotive electronics, industrial control systems, renewable energy inverters, and telecommunications infrastructure. The 1206 package size and GRM series specifications make this component suitable for engineers designing robust, long-lifecycle products where component reliability and stable performance over time are paramount. When selecting this part, engineers benefit from Murata's established quality standards and the component's proven performance in field applications across multiple industries.
