RN122-2-02-6M8

Overview

The Schaffner RN122-2-02-6M8 is a current compensated common mode choke designed for printed circuit board mounting. It features a horizontal orientation with through-hole termination and utilizes ferrite core material. The component provides an inductance of 6.8 mH at a test frequency of 10 kHz, supporting a maximum DC current of 2 A. Its maximum DC resistance is specified at 156 mOhms. The device operates within a temperature range of -40°C to +100°C and carries UL certification.

Feature Summary

• Provides effective attenuation of electromagnetic interference through common mode filtering capabilities
• Utilizes a current compensated design suitable for single-channel applications
• Constructed with ferrite core material for stable magnetic performance

Applications

• Electromagnetic compatibility filtering in electronic equipment
• Power supply input stages requiring EMI suppression
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the manufacturer part number RN122-2-02-6M8 against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the horizontal package style and through-hole pin configuration match the target PCB layout requirements. Check for specific RoHS compliance status and any applicable safety certifications such as UL recognition relevant to the intended end-use environment.

Selection Notes

Select this component when a horizontal form factor is required for space-constrained PCB layouts. Ensure the application current does not exceed the 2 A rating to prevent saturation. Verify that the 6.8 mH inductance value meets the specific noise filtering requirements at the operating frequency. Consider the thermal management needs given the 100°C maximum operating temperature limit.

Part Context

This component belongs to the RN series of common mode chokes manufactured by TE Connectivity under the Schaffner brand. The series offers various inductance and current ratings tailored for different EMC filtering needs. The RN122 variant specifically denotes a horizontal mounting style with defined terminal spacing, distinguishing it from vertical counterparts in the same product family.

Replacement Considerations

Cross-reference with other RN series parts for alternative inductance values if specifications differ. Verify mechanical footprint compatibility before substituting with similar components from other manufacturers.
