GRM21BR71E475KA73L: High-Performance Multilayer Ceramic Capacitor for Advanced Electronics

The GRM21BR71E475KA73L features a precisely calibrated 4.7 μF capacitance, optimized for high-frequency and high-power applications. Housed in a compact 2125 (2.0mm x 1.25mm) surface-mount package, it offers a space-saving solution for high-density printed circuit boards (PCBs), enabling seamless integration into miniaturized devices. The capacitor utilizes X7R dielectric material, providing stable capacitance performance across a wide temperature range from -55°C to +125°C, with a capacitance change of ±15% over the temperature span. The 1E notation indicates a rated voltage of 25V, ensuring safe operation in standard circuit configurations. Its low equivalent series resistance (ESR) minimizes power losses, while the high self-resonant frequency enhances efficiency in high-speed circuits. The K tolerance level (±10%) ensures consistent capacitance values for reliable circuit operation, and the A73L suffix denotes specific packaging and terminal features that enhance soldering reliability and mechanical durability.

This MLCC excels in high-frequency environments, offering excellent impedance characteristics that effectively filter electrical noise and maintain signal integrity. Its X7R dielectric balances thermal stability with cost-effectiveness, making it ideal for applications where moderate capacitance change with temperature is acceptable, such as power supply decoupling, signal conditioning, and high-speed data transmission circuits. The GRM21BR71E475KA73L also demonstrates superior mechanical endurance, withstanding vibrations, thermal cycles, and electrical surges without performance degradation. Additionally, its lead-free and RoHS-compliant design adheres to international environmental standards, ensuring sustainable manufacturing practices.

In consumer electronics, the GRM21BR71E475KA73L optimizes power delivery in smartphones, tablets, and wearables, enhancing battery life by stabilizing voltage fluctuations in processor and display circuits. In the automotive industry, it is integrated into engine control units (ECUs), advanced driver-assistance systems (ADAS), and in-car infotainment systems, where its reliability under harsh conditions-including temperature extremes and mechanical vibrations-ensures consistent system performance. For industrial electronics, the capacitor supports the efficient functioning of programmable logic controllers (PLCs), sensors, and automation equipment, reducing downtime in manufacturing environments. Moreover, in telecommunications and networking, it filters noise in 5G base stations, routers, and data center switches, enabling seamless high-speed data transmission.
