Overview：

The Murata GRM31CC80G227ME11L is a chip monolithic multilayer ceramic capacitor (MLCC) from the GRM series, designed for general electronic equipment. This device features a compact 3216 package (dimensions: 3.2mm × 1.6mm × 1.6mm) with a high capacitance value of 220µF, making it an ideal solution for space-constrained applications such as power supply decoupling, smoothing, and energy storage.

This capacitor utilizes the X6S temperature characteristic (EIA Class II), offering a capacitance change of ±22% over an operating temperature range of –55°C to +105°C (reference temperature 25°C). It is rated for a DC voltage of 4V with a capacitance tolerance of ±20%. The terminations are tin-plated to ensure excellent solderability, and the device is supplied in embossed tape-and-reel packaging (φ180mm reel, W8P4, 2000 pieces per reel), suitable for automated surface-mount assembly.

The product complies with JIS C 5101 and IEC60384 standards and is specifically designed for mobile devices and portable consumer electronics (e.g., smartphones, tablets, digital cameras) with a typical lifetime of less than 5 years. For applications requiring extended lifetime, voltage and temperature derating guidelines are recommended. Key electrical characteristics include: insulation resistance of ≥2000MΩ or 50Ω·F (whichever is smaller), dissipation factor of ≤0.1 (measured at 1±0.1kHz, 1.0±0.2Vrms for C≤10µF), and voltage proof of 250% of rated voltage.

This product is intended for reflow soldering processes. Proper attention must be paid to mounting position, solder amount, and PCB design to avoid mechanical stress that could lead to chip cracking. Recommended storage conditions are temperature +5°C to +40°C and relative humidity 20% to 70%.
