RN112-0.5-02-18M

Overview

The Schaffner RN112-0.5-02-18M is a current compensated common mode choke from the RN series, designed for PCB mounting via through-hole termination. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical parameters include an inductance of 18 mH with tolerances of -30% and +50%, a maximum DC current rating of 0.5 A, and a maximum DC resistance of 1100 mOhms. The component is tested at 10 kHz and has dimensions of 17.7 mm x 17.1 mm x 12.6 mm.

Feature Summary

Provides common mode current compensation using two windings on a toroidal ferrite core.

Applications

EMC/EMI filtering for medical devices
AC power line noise suppression

Procurement Notes

Verify the manufacturer part number against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical characteristics, as variations may exist within the RN series. Cross-reference datasheets for precise tolerance and thermal ratings before integration.

Selection Notes

Select this component for applications requiring horizontal PCB mounting and through-hole termination. Ensure the circuit design accommodates the 0.5 A current limit and 18 mH inductance. Verify that the physical footprint of 17.7 mm x 17.1 mm fits the board layout constraints.

Part Context

This component belongs to the RN series of common mode chokes manufactured by TE Connectivity / Schaffner. The series utilizes toroidal ferrite cores to deliver current compensated inductance, suitable for suppressing electromagnetic interference in single-phase AC power lines.

Replacement Considerations

RN122-1-02-18M offers similar inductance but higher current capacity (1A) and larger dimensions. RN112-2-02-1M0 provides lower inductance (1mH) with higher current handling (2A). Verify pin compatibility and thermal performance when substituting.
