RN122-1.5-02

Overview

The Schaffner RN122-1.5-02 is a current-compensated common mode choke designed for printed circuit board mounting via through-hole technology. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical specifications include an inductance of 10 mH at a test frequency of 10 kHz, with a tolerance of -30% to +50%. The component supports a maximum DC current of 1.5 A and exhibits a typical DC resistance of 220 mOhms. Its physical dimensions are approximately 27 mm x 28 mm x 16.5 mm.

Feature Summary

• Provides RFI suppression through current-compensated common mode filtering.
• Utilizes a ferrite core for effective electromagnetic interference reduction.
• Designed for reliable operation across a wide industrial temperature range.

Applications

• Power supply input filtering
• EMI suppression in electronic equipment
• Signal line protection

Procurement Notes

Verify the specific part number against official TE Connectivity or Schaffner documentation to ensure accuracy. Confirm that the required inductance and current ratings match the application design. Check for RoHS compliance status as indicated in the manufacturer's datasheet. Ensure the through-hole package dimensions fit the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a 10 mH common mode choke with 1.5 A current handling is required for horizontal PCB mounting. Consider the -30% to +50% inductance tolerance during circuit design. Verify that the unshielded construction does not interfere with nearby sensitive components. Compare thermal performance requirements against the +100°C maximum operating temperature limit.
