What is GRM21BC81H475KE11K MLCC?
The GRM21BC81H475KE11K is an SMD Capacitor manufactured by Murata. Key specs include 4.7µF capacitance, 50V rating, X6S dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable capacitance across temperature variations in medium-voltage circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 4.7µF at 50V provides sufficient bulk capacitance for ripple suppression while the X6S dielectric maintains stable capacitance from -55°C to +105°C.
- Power Supply Decoupling for Industrial Sensors: The 0805 package fits standard pick-and-place lines, and the ±10% tolerance ensures consistent performance in harsh environments.
- Automotive Infotainment Modules: With 50V rating and X6S characteristics, this MLCC supports input rail filtering where both voltage margin and thermal stability are critical.
Key Features & Advantages
- High Capacitance Density: 4.7µF in 0805 enables space savings on dense PCBs without sacrificing performance.
- Wide Temperature Range: X6S dielectric ensures reliable operation from -55°C to +105°C, ideal for variable ambient conditions.
- 50V Voltage Rating: Provides ample headroom for 12V, 24V, and even 48V rails, reducing derating concerns.
Frequently Asked Questions
- Q: What makes GRM21BC81H475KE11K different from a standard X5R capacitor?
A: The X6S dielectric offers improved capacitance stability over temperature compared to X5R, particularly at higher temperatures up to +105°C, while maintaining the same 4.7µF rating. - Q: Is GRM21BC81H475KE11K RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply and flexible quantity options for this Murata MLCC.
