What is GRM31CR72E473KW03L MLCC?
The GRM31CR72E473KW03L is a high-voltage multilayer ceramic capacitor from Murata. Key specs include 0.047µF capacitance, 250V rated voltage, X7R dielectric, and ±10% tolerance in a 1206 package. RoHS compliant, it delivers stable capacitance and reliable filtering in medium-to-high voltage DC circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Filtering: The 250V rating and 0.047µF value provide effective high-frequency noise suppression on 48V or 100V bus rails without derating concerns.
- Industrial Sensor Power Decoupling: X7R dielectric ensures stable capacitance over -55°C to +125°C, matching the thermal demands of factory automation and process control modules.
- LED Lighting Driver Snubber Circuits: The compact 1206 footprint handles 250V peak voltages in flyback snubbers, reducing ringing while saving board space.
Key Features & Advantages
- 250V Voltage Rating: Enables direct use in 48V and 100V rails without series stacking, simplifying layout and reducing component count.
- X7R Dielectric Stability: Capacitance change within ±15% across the full temperature range ensures consistent filter corner frequencies in harsh environments.
- 1206 Industry-Standard Package: Compatible with automated pick-and-place assembly and widely supported in existing PCB footprints for fast time-to-market.
Frequently Asked Questions
- Q: What makes GRM31CR72E473KW03L different from a standard 1206 MLCC?
A: Its 250V rating is significantly higher than typical 50V or 100V 1206 parts, allowing direct use in higher-voltage rails while maintaining the same footprint. - Q: Is GRM31CR72E473KW03L 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 pre-production runs.
