Procurement Notes
Verify the manufacturer part number against official TE Connectivity / Schaffner documentation to ensure authenticity. Confirm that the received components match the specified 39 mH inductance and 700 mA current rating. Check for physical damage to leads and verify RoHS compliance status as required by project specifications before integration into production assemblies.
Selection Notes
Select this component when a 39 mH common mode choke with a 700 mA current capacity is required for vertical PCB mounting. Ensure the application environment stays within the -40°C to +100°C operating temperature range. Consider the 1.15 Ohm DC resistance impact on voltage drop and the specific tolerance requirements for the target circuit design.
Part Context
This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The RN series provides standardized solutions for electromagnetic interference suppression in various electronic applications. This specific model represents a standard inductance value within the family, offering a balance between filtering performance and current handling capabilities for general-purpose use.
Replacement Considerations
RN218-0.6-02-47M and RN218-0.9-02-27M are related models within the same product family. Verify compatibility based on specific inductance and current requirements before substitution.
