RN112-1.5-02-3M3

Overview

The Schaffner RN112-1.5-02-3M3 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. The component provides an inductance of 3.3 mH with a tolerance of -30% to +50%, tested at 10 kHz. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 102 mOhms. The physical dimensions are 18 mm x 12.5 mm x 20 mm, and it is unshielded.

Feature Summary

Provides common mode noise suppression through current compensated choke design
Utilizes ferrite core material for electromagnetic interference filtering
Supports vertical or horizontal PCB mounting configurations

Applications

Electromagnetic compatibility (EMC) filtering in electronic circuits
Radio frequency interference (RFI) suppression applications
Power supply input stages requiring common mode noise reduction

Procurement Notes

Verify the manufacturer part number RN112-1.5-02-3M3 against official TE Connectivity / Schaffner documentation to confirm specifications. Ensure the required inductance, current rating, and package dimensions match the target design constraints. Cross-reference the alias 816546-SF if applicable. Confirm RoHS compliance status through the specific datasheet provided by the manufacturer before procurement.

Selection Notes

Select this component when a 3.3 mH inductance and 1.5 A current rating are required for common mode noise suppression. The through-hole package suits designs needing robust mechanical attachment. Verify that the unshielded construction does not interfere with nearby sensitive components. Ensure the operating environment stays within the specified -40°C to +100°C temperature range for reliable performance.

Part Context

This component belongs to the RN series of EMC/RFI chokes manufactured by TE Connectivity / Schaffner. The series offers various inductance and current combinations for different filtering needs. The RN112-1.5-02-3M3 specifically targets applications requiring moderate inductance values with through-hole termination for standard PCB assembly processes.
