EXC-24CP221U

Common Mode Chokes Overview

The EXC-24CP221U is a surface-mount common mode noise filter manufactured by Panasonic Industry. It belongs to the EXC24C series and is designed for high-current applications. The component features a 0504 (1210 metric) package with dimensions of 1.25 mm length, 1 mm width, and 0.5 mm height. Key electrical specifications include an impedance of 220 Ohms with a 25% tolerance and a maximum DC resistance of 400 mOhms. It supports a maximum DC current of 350 mA and operates within a temperature range of -40°C to +85°C.

Common Mode Chokes Feature Summary

• High current handling capability suitable for demanding power line filtering
• Compact surface-mount design for efficient PCB space utilization
• Unshielded construction for standard noise suppression tasks

Common Mode Chokes Applications

• Power supply input filtering in electronic devices
• Noise suppression on data lines requiring high current tolerance
• Common mode interference reduction in compact consumer electronics

Common Mode Chokes Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating any new product development projects. Confirm that the 0504 package footprint matches existing board layouts. Ensure the 350 mA current rating meets circuit requirements. Check RoHS compliance documentation for regulatory adherence. Validate supplier authenticity as Panasonic Industry is the sole manufacturer.

Common Mode Chokes Selection Notes

Select this component when high current capacity is required alongside common mode noise filtering. Compare against the EXC-24CB221U if lower current ratings are acceptable, noting its higher DC resistance. Ensure the unshielded nature aligns with electromagnetic interference requirements. Verify that the 220 Ohm impedance provides sufficient attenuation for the target frequency spectrum.
