Procurement Notes

Verify the manufacturer part number RN112-1.2-02-6M8 against official TE Connectivity or Schaffner documentation to confirm specifications. Ensure compatibility with PCB footprint requirements, specifically the 17.7 mm x 17.1 mm x 12.6 mm package and 0.8 mm lead diameter. Confirm that the 1.2 A current rating and 6.8 mH inductance meet circuit design needs. Check for RoHS compliance status as indicated in official datasheets.

Selection Notes

Select this component when horizontal mounting space is constrained, given its 12.6 mm height profile. Choose based on the required 6.8 mH inductance and 1.2 A current handling capability. Consider the unshielded nature and ferrite core construction for standard EMI applications. Verify the -40°C to +100°C operating range suits the environmental conditions. Compare against other RN series variants if different inductance or current ratings are needed.
