What is GRM21BR61H475KE51K MLCC?
The GRM21BR61H475KE51K is a SMD capacitor manufactured by Murata (村田). Key specs include CAP CER 4.7UF 50V X5R 0805±10%. RoHS compliant, it is designed for stable decoupling and filtering in mid-voltage circuits.
✔ RoHS Compliant / ✔ 0805 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Power Rail Decoupling: With 4.7UF capacitance and 50V rating, it smooths voltage ripple on 12V and 24V buses while keeping ESR low in a compact 0805 footprint.
- DC-DC Converter Output Filtering: The X5R dielectric maintains capacitance stability across -55°C to +85°C, ensuring consistent filtering performance under load changes.
- Industrial Sensor Interface: The ±10% tolerance provides reliable AC coupling and noise bypass in sensor signal chains operating at bus voltages up to 50V.
Key Features & Advantages
- High Voltage Margin: The 50V rating exceeds typical 3.3V/5V logic rails, offering robust headroom for automotive and industrial supply lines.
- Compact 0805 Form Factor: Delivers 4.7UF in a small package, freeing PCB space for dense layouts without sacrificing bulk capacitance.
- Stable X5R Dielectric: Capacitance change within ±15% over -55°C to +85°C ensures predictable circuit behavior across temperature extremes.
Frequently Asked Questions
- Q: What makes GRM21BR61H475KE51K different from a standard MLCC?
A: It combines a high 4.7UF capacitance with a 50V rating in an 0805 package — a balance that many general-purpose capacitors do not offer, making it ideal for mid-voltage decoupling. - Q: Is GRM21BR61H475KE51K 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 small-batch flexibility for quick-turn builds.
