RN122-0.8-02

Overview

The Schaffner RN122-0.8-02 is a horizontal through-hole common mode choke from the RN series, designed for PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. The component has a maximum DC current rating of 0.8 A and a maximum DC resistance of 39 mOhms. Inductance is specified at 39 mH with tolerances of -30% and +50%. Measuring 27 mm x 28 mm x 16.5 mm, it is unshielded and rated UL 94V-0.

Feature Summary

Horizontal surface-mount compatible design for efficient PCB integration
Current compensated construction for effective noise suppression
High potential insulation strength between windings and housing

Applications

Power supply input filtering
DC/DC converter stages
Portable device power regulation

Procurement Notes

Verify the specific inductance suffix (e.g., 39M) as part numbers in this series vary by value. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the 0.8A current rating meets circuit requirements. Check for alternate pin configurations if space is constrained.

Selection Notes

Select based on required inductance and current handling capabilities. The RN122 form factor suits applications needing horizontal footprint efficiency. Verify thermal performance at maximum load. Compare against similar RN series variants for precise electrical matching.

Part Context

This component belongs to the Schaffner RN series of common mode chokes. These are widely used in EMC/RFI suppression for electronic equipment. The series offers various inductance values tailored for different noise frequencies and current loads.

Replacement Considerations

RN122-0.8-02-39M is a confirmed equivalent designation. Cross-reference with other RN122 variants for identical mechanical dimensions but different electrical parameters.
