RN212-0.5-02-27M

Overview

The Schaffner EMC RN212-0.5-02-27M is a vertical through-hole common mode choke designed for PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical parameters include an inductance of 27 mH with a tolerance of -30% to +50%, measured at a test frequency of 10 kHz. The component supports a maximum DC current of 0.5 A and exhibits a maximum DC resistance of 1200 mOhms. Its physical dimensions are 18 mm x 12.5 mm x 20 mm, and it weighs approximately 8 grams.

Feature Summary

Provides current compensated inductance using two windings on a toroidal ferrite core to suppress common mode noise.

Applications

Electromagnetic interference (EMI) suppression in AC power circuits
Filtering common mode noise in switch-mode power supplies
Noise reduction in industrial automation equipment

Procurement Notes

Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm electrical ratings and mechanical dimensions. Ensure compatibility with the target PCB footprint and thermal requirements. Cross-reference datasheets for any updates regarding RoHS compliance status or manufacturing changes. Confirm that the 0.5A current rating meets the application's operational needs under all expected conditions.

Selection Notes

Select this component when a compact, vertically mounted common mode choke is required for low-current AC line filtering. The 27 mH inductance offers significant attenuation for high-frequency noise. Consider the unshielded design and operating temperature limits when placing the component near heat sources or sensitive circuitry. Verify that the through-hole termination style matches the assembly process.

Part Context

This component belongs to the RN series of common mode chokes manufactured by TE Connectivity / Schaffner. The series utilizes toroidal ferrite cores with wound inductors to provide current compensation. These chokes are typically connected in series with the phase or neutral lines of AC power supplies to effectively reduce asymmetric electromagnetic interference.
