What is KCA55L7UMF222KL01L MLCC?
The KCA55L7UMF222KL01L is a high-voltage SMD capacitor manufactured by Murata (村田). Key specs include 2200pF capacitance, 250V rating, U2J dielectric, and ±10% tolerance. RoHS compliant, it is designed for stable performance in demanding power and signal conditioning circuits.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC Converter Snubbers: The 250V rating and 2200pF value effectively damp high-frequency ringing and voltage spikes in switching power stages.
- High-Voltage Coupling: U2J’s low capacitance change with DC bias ensures signal integrity in 250V communication interfaces and sensor front-ends.
- Timing & Tuning Circuits: U2J’s flat temperature coefficient (±120ppm/°C typical) makes the 2200pF capacitor ideal for stable oscillator or filter networks.
Key Features & Advantages
- High Voltage Rating (250V): Enables use in 48V and higher bus systems without derating concerns.
- U2J Dielectric Stability: Provides low ESR and minimal capacitance shift under voltage and temperature extremes, outperforming X7R in high-Q applications.
- Compact SMD Package: Surface-mount format reduces board space consumption and supports automated assembly for production efficiency.
Frequently Asked Questions
- Q: What makes KCA55L7UMF222KL01L different from a standard MLCC?
A: Its U2J dielectric delivers superior capacitance stability under high DC voltage (250V) compared to X7R or X5R parts, which can lose significant capacitance above 100V. - Q: Is KCA55L7UMF222KL01L 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.
