What is GRM21BZ71E475KE15K MLCC?
The GRM21BZ71E475KE15K is a precision SMD capacitor manufactured by Murata. Key specs include 4.7µF capacitance, 25V DC rating, X7R dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable decoupling and filtering in space-constrained circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 4.7µF capacitance in a 25V-rated X7R ceramic ensures low ESR and stable bulk storage for 5V or 3.3V rails, suppressing ripple without needing electrolytic caps.
- Digital IC Power Decoupling: Compact 0805 package fits dense PCB layouts near SoCs or FPGAs, while the X7R characteristic guarantees capacitance variation within ±15% over -55°C to +125°C.
- Automotive Body Electronics: Murata’s reliability and the 25V withstand margin make it suitable for 12V battery-line bypass in infotainment or lighting control modules.
Key Features & Advantages
- Balanced Capacitance & Voltage: 4.7µF at 25V provides solid energy storage for mid-power rails while keeping the 0805 footprint small.
- X7R Thermal Stability: Minimal capacitance shift across temperature extremes ensures consistent performance under varying ambient conditions.
- ±10% Tight Tolerance: Reduces design margin waste, enabling precise filter cutoff frequencies and predictable transient response.
