MLCC GRM31BR72E223KW01L

What is GRM31BR72E223KW01L MLCC?

The GRM31BR72E223KW01L is a 0.022µF SMD capacitor manufactured by Murata. Key specs include 250V rated voltage, X7R dielectric, and ±10% tolerance in a 1206 footprint. RoHS compliant, it is designed for stable capacitance over temperature in medium-voltage decoupling and filtering tasks.

✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC-DC Converter Output Filtering: Its 250V rating and 0.022µF capacitance ensure effective ripple suppression in high-voltage power modules while maintaining X7R stability across -55°C to +125°C.
• Industrial Sensor Interface Circuits: The 1206 package provides robust solder joint reliability in harsh environments, and the X7R dielectric guarantees predictable behavior under temperature fluctuations common in factory automation.
• Telecom Line Driver Decoupling: Tight ±10% tolerance keeps parasitic effects consistent across multiple channels, while the 250V margin safely handles transient surges on communication lines.

Key Features & Advantages

• 250V Voltage Rating: Offers double the typical 100-200V margin for 48V telecom or 120V industrial rails, reducing derating concerns and improving long-term reliability.
• X7R Dielectric Stability: Capacitance change within ±15% over the full temperature range ensures predictable filter corner frequencies in automotive and power applications.
• 1206 Standard Footprint: Compatible with mainstream pick-and-place equipment, allowing easy drop-in replacement without PCB redesign while providing adequate creepage distance for 250V operation.

Frequently Asked Questions

1. Q: What makes GRM31BR72E223KW01L different from a standard 0.022µF X7R?
   A: Its 250V rating is significantly higher than typical 50V or 100V X7R MLCCs, making it suitable for 150V-200V bus voltages where standard parts would require series stacking or derating.
2. Q: Is GRM31BR72E223KW01L RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. 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 splits for pre-production validation.
