RN116-1.7-02-4M0

Overview

The Schaffner RN116-1.7-02-4M0 is a horizontal through-hole common mode choke designed for power line filtering. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical parameters include an inductance of 4 mH with tolerances of -30% and +50%, measured at a test frequency of 10 kHz. The component supports a maximum DC current of 1.7 A and exhibits a maximum DC resistance of 87 mOhms. Its physical dimensions are 21.5 mm x 22.5 mm x 13.2 mm, and it is classified as an unshielded current compensated choke.

Feature Summary

• Provides common mode noise suppression for two-line power circuits using a ferrite core structure.
• Designed for horizontal PCB mounting via through-hole termination pins.
• Functions as a current compensated choke to maintain signal integrity while filtering interference.

Applications

• Power supply input filtering
• Electromagnetic compatibility (EMC) mitigation in electronic equipment
• RFI suppression in industrial control systems

Procurement Notes

Verify the specific part number RN116-1.7-02-4M0 against official TE Connectivity or Schaffner documentation to confirm pinout orientation and tolerance specifications. Ensure that the required operating current does not exceed the rated 1.7 A limit and that the PCB layout accommodates the specified horizontal footprint dimensions. Cross-reference datasheet revisions to guarantee compliance with current environmental directives.

Selection Notes

Select this component when a 4 mH inductance value is required for common mode noise reduction in applications handling up to 1.7 A. The horizontal form factor suits designs requiring low profile mounting on printed circuit boards. Consider the wide inductance tolerance range when designing precise filter cutoff frequencies. Verify thermal management requirements given the maximum operating temperature of 100°C.

Part Context

This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is characterized by horizontal construction and through-hole technology, targeting general-purpose EMI suppression in power lines. The RN116 designation indicates specific dimensional and electrical characteristics within this product family.

Replacement Considerations

Check for direct substitutes such as RN116 variants with different inductance values if electrical parameters do not match. Verify mechanical compatibility with existing PCB footprints before substituting with other horizontal choke models from different manufacturers.
