RN212-1.2-02-6M8

Overview

The Schaffner RN212-1.2-02-6M8 is a current-compensated common mode choke 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 6.8 mH at a test frequency of 10 kHz, with a tolerance of -30% and +50%. The component supports a maximum DC current of 1.2 A and exhibits a maximum DC resistance of 722 mOhms. Its physical dimensions are 15.0 mm in length, 10.0 mm in width, and 20.0 mm in height, weighing approximately 8 grams.

Feature Summary

• Provides high saturation resistance for effective noise suppression
• Utilizes a ferrite core material for magnetic performance
• Designed as a current-compensated choke for single-channel applications

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Power supply input stages requiring common mode noise reduction
• Signal integrity protection in sensitive communication interfaces

Procurement Notes

Verify the specific part number suffix against official TE Connectivity or Schaffner documentation to confirm exact electrical tolerances and pin configuration. Ensure that the through-hole footprint matches the target PCB layout dimensions of 15.0 mm by 10.0 mm. Confirm compliance requirements such as RoHS status directly from the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 6.8 mH inductance value is required for common mode noise attenuation at 10 kHz. The 1.2 A current rating must align with the circuit's maximum operating current to prevent saturation. Consider the unshielded design and vertical mounting profile for spatial constraints on the printed circuit board assembly.

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 its use in EMI suppression applications where high saturation resistance is critical. The RN212 variant specifically denotes a through-hole mounted device with defined dimensional standards for industrial electronics integration.

Replacement Considerations

Cross-reference with other RN series variants such as RN212-1.5-02-3M3 or RN212-2-02-1M8 if different current or inductance ratings are needed. Verify that any substitute maintains the same 15.0 mm x 10.0 mm x 20.0 mm footprint and through-hole termination style to ensure mechanical compatibility.
