Overview
The Schaffner EMC Inc. RN112-1.5-02 is a current compensated common mode choke designed for power line filtering applications. It features an inductance of 3.3 mH and supports a maximum DC current of 1.5 A. The component has a maximum DC resistance of 102 mOhms and utilizes a ferrite core material. It is constructed for through-hole PCB mounting with vertical orientation. The device operates within a temperature range of -40°C to +100°C and measures 18 mm x 12.5 mm x 20 mm.
Feature Summary
- Provides common mode noise suppression for power lines
- Utilizes a current compensated choke design
- Features a vertical through-hole mounting style
Applications
- Power line filtering
- Electromagnetic interference suppression
- Electronic equipment input stages
Procurement Notes
Verify the specific suffix designation, as the RN112-1.5-02-3M3 variant is documented with identical electrical parameters. Confirm that the required package orientation matches the vertical configuration specified for this series. Ensure the application current does not exceed the rated 1.5 A limit to maintain performance integrity.
Selection Notes
Select this component when a 3.3 mH inductance value is required for single-phase power line filtering. The 1.5 A current rating suits moderate power applications. Verify that the unshielded construction aligns with the system's electromagnetic compatibility requirements and spatial constraints on the printed circuit board.
Part Context
This component belongs to the RN series of common mode chokes manufactured by TE Connectivity / Schaffner. The series offers various inductance and current ratings tailored for different power line filtering needs. These components are widely used in industrial and consumer electronics to mitigate conducted emissions.
Replacement Considerations
The part number RN112-1.5-02-3M3 serves as a confirmed substitute with matching specifications. Other RN series variants may be considered if inductance or current ratings differ from the original design requirements.
