What is KRM55TR73A224MH01K MLCC?
The KRM55TR73A224MH01K is a high-voltage SMD capacitor manufactured by Murata. Key specs include a capacitance of 0.22µF, a rated voltage of 1kV (1000V), X7R dielectric, and ±20% tolerance. RoHS compliant, it is designed for power circuits requiring stable filtering in compact form.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Output Smoothing: The 1kV rating and 0.22µF capacitance allow effective ripple suppression in high-voltage power supplies, while X7R provides stable capacitance over temperature.
- Snubber Networks: With ±20% tolerance and high breakdown voltage, this MLCC is ideal for limiting voltage spikes in switching circuits, reducing EMI.
- Industrial Power Conditioners: Murata’s robust construction withstands harsh environments, and the SMD package enables automated assembly for high-volume production.
Key Features & Advantages
- High Voltage Rating (1kV): Enables use in power conversion stages without derating concerns, improving reliability.
- X7R Dielectric: Offers ±15% capacitance change from -55°C to +125°C, ensuring consistent performance across temperature ranges.
- Compact 0.22µF in SMD: Saves board space compared to stacked film capacitors while delivering the required capacitance for decoupling.
Frequently Asked Questions
- Q: What makes KRM55TR73A224MH01K different from a standard 50V MLCC?
A: Its 1kV voltage rating is significantly higher, allowing direct use in high-voltage rails without series configuration. The ±20% tolerance also gives cost advantage in less critical filtering roles. - Q: Is KRM55TR73A224MH01K 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.
