What is GRM21BB31H475KE51L MLCC?
The GRM21BB31H475KE51L is an SMD capacitor from Murata. Key specs include a capacitance of 4.7F, voltage rating of 50V, temperature characteristic B, and tolerance ±10%. RoHS compliant, it is designed for applications requiring exceptionally high capacitance in a compact 0805 footprint.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power Supply Hold-Up Circuits: With 4.7F capacitance at 50V, this MLCC provides substantial energy storage, enabling stable output during brief power interruptions or load transients.
- High-Density Decoupling: Its ultra-high capacitance (4.7F) in an 0805 package reduces the number of parallel capacitors needed on dense PCBs, saving board space while maintaining low ESR.
- Energy Harvesting Buffers: The combination of 4.7F and 50V makes this part ideal for temporary storage in low-power IoT endpoints, allowing bursts of operation without external supercaps.
Key Features & Advantages
- 4.7F Capacitance in 0805: Delivers orders of magnitude more capacitance than conventional MLCCs, enabling novel circuit architectures.
- 50V Voltage Rating: Suitable for 12V, 24V, and even 48V bus applications with adequate derating margin.
- Murata Consistency: Tight tolerance (±10%) and reliable B-characteristic ensure predictable performance across temperature and aging.
Frequently Asked Questions
- Q: What makes GRM21BB31H475KE51L different from a standard MLCC?
