RN122-4-02-3M3

Overview

The Schaffner RN122-4-02-3M3 is a horizontal through-hole common mode choke designed for PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical specifications include an inductance of 3.3 mH, a maximum DC current rating of 4 A, and a maximum DC resistance of 46 mOhms. The component has a tolerance of -30% to +50% and is tested at 10 kHz. Its physical dimensions are 27 mm x 28 mm x 16.5 mm.

Feature Summary

Horizontal surface mount configuration for efficient PCB layout
Current compensated design utilizing ferrite core material
Unshielded construction suitable for general EMI suppression

Applications

Power supply input filtering
Battery charger circuits
Portable electronic device power stages

Procurement Notes

Verify the manufacturer part number against official TE Connectivity or Schaffner documentation to confirm specifications. Ensure the ordering suffix matches the required pin configuration and tolerance. Cross-reference datasheets for thermal derating curves and mechanical footprint details before finalizing procurement decisions.

Selection Notes

Select this component when a high-current common mode choke with 3.3 mH inductance is required for horizontal PCB integration. Consider the 4 A current rating and low DC resistance for applications demanding minimal voltage drop. Verify that the unshielded design meets the electromagnetic compatibility requirements of the target system without causing interference.

Part Context

This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series offers various current ratings and inductance values for EMI suppression in power electronics. The RN122-4-02-3M3 specifically addresses needs for higher current handling in compact horizontal form factors.

Replacement Considerations

Check for direct substitutes within the RN series with matching 3.3 mH inductance and 4 A rating. Verify pinout compatibility and dimensional constraints for existing PCB footprints. Consult manufacturer cross-reference lists for approved alternative part numbers.
