GRM32DC72A475KE01L

The Murata GRM32DC72A475KE01L is a chip monolithic ceramic capacitor designed for general-purpose electronic equipment. It offers a nominal capacitance of 4.7 µF with a tolerance of ±10%, and is rated for a maximum DC voltage of 100 V. The capacitor uses an X7S temperature coefficient (EIA code), which specifies a capacitance change of ±22% over the operating temperature range of -55°C to +125°C.

This component is housed in a 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm × 2.5 mm × 2.0 mm (length × width × thickness). The maximum thickness is 2.2 mm. It is supplied on 8 mm embossed tape with 4 mm pitch, available in reels of 1000 pieces (180 mm reel) or 4000 pieces (330 mm reel).

Key electrical characteristics include a maximum dissipation factor of 0.1 (measured at 1 kHz, 0.5 Vrms), a minimum insulation resistance of 50 Ω·F (measured at rated DC voltage for 1 minute), and a dielectric withstanding voltage of 250% of rated voltage (applied for 1-5 seconds). These parameters make it suitable for power supply decoupling, filtering, and energy storage applications in general electronic circuits.

The capacitor is designed for surface-mount assembly and is suitable for general-purpose applications where stable capacitance over a wide temperature range is required. Its X7S dielectric provides a balance between capacitance density and temperature stability, making it a practical choice for many board-level designs.
