RN122-2.5-02

Overview

The Schaffner RN122-2.5-02 is a horizontal, through-hole common mode choke designed for power line filtering applications. It features a ferrite core and supports two lines with a typical inductance of 5.6 mH at 1 kHz. The component handles a maximum current rating of 2.5 A and operates within a temperature range of -40°C to +125°C. It measures approximately 16.80 mm in height and includes four pins. The unit is UL 94 V-0 flammability rated and undergoes a 4000 VAC high potential test between windings.

Feature Summary

• Horizontal mounting configuration with four-pin through-hole termination
• Current compensated design for effective noise suppression on power lines
• High dielectric strength verified by 4000 VAC winding-to-winding testing
• Flame retardant housing meeting UL 94 V-0 standards

Applications

• Power supply input filtering
• Electromagnetic interference suppression in electronic equipment
• Common mode noise reduction in AC/DC conversion stages

Procurement Notes

Verify the specific manufacturer source, as TE Connectivity acquired Schaffner EMC. Confirm that the part number RN122-2.5-02 corresponds to the exact 5.6 mH specification and 2.5 A rating required for your circuit design. Check for any updated datasheets or obsolescence notices from the current manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a robust, high-current common mode choke is needed for horizontal PCB mounting. Ensure the 5.6 mH inductance value aligns with the target frequency range for noise attenuation. Verify that the 2.5 A current rating exceeds the maximum load current of the application to prevent saturation and ensure reliable operation under thermal stress up to 125°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, suitable for industrial and commercial power electronics where space constraints allow for larger form factors compared to surface mount alternatives.
