RN102-1-02-3M0

Overview

The Schaffner RN102-1-02-3M0 is a through-hole common mode choke from the RN series, designed for electromagnetic interference suppression. It features an inductance of 3 mH and supports a maximum DC current of 1 A with a DC resistance of 210 mΩ. The component operates within a temperature range of -40°C to +100°C and utilizes a horizontal package configuration.

Feature Summary

• Provides effective common mode noise attenuation for single-channel applications
• Utilizes ferrite core material for stable magnetic performance
• Designed for direct printed circuit board mounting via through-hole technology

Applications

• Power supply input filtering
• Signal line noise suppression
• General-purpose EMI/EMI mitigation in electronic equipment

Procurement Notes

Verify the specific manufacturer designation, as TE Connectivity and Schaffner branding may appear on identical components. Confirm the physical orientation matches the horizontal pin layout required by the design. Ensure the thermal rating aligns with the operational environment limits specified in the official datasheet.

Selection Notes

Select this component when a 3 mH inductance value is required for low-current circuits up to 1 A. The horizontal form factor suits space-constrained boards where vertical height must be minimized. Verify that the 210 mΩ resistance meets the voltage drop constraints of the target application circuit.

Part Context

This part belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now integrated into TE Connectivity's portfolio. The series offers various inductance and current ratings for diverse filtering needs across industrial and consumer electronics markets.

Replacement Considerations

RN102-1-02-3M0 is functionally equivalent to other RN102 variants with matching electrical parameters. Cross-reference with TE Connectivity documentation for exact mechanical fit before substitution.
