RT8122-63-0M5

Overview

The Schaffner RT8122-63-0M5 is a current compensated common mode choke designed for horizontal PCB mounting. It features a ferrite core and through-hole termination with a 45 mm x 45 mm x 34 mm package. The component provides an inductance of 500 µH at 100 kHz, supporting a maximum DC current of 63 A. Its low DC resistance is 1.1 mOhms, ensuring minimal power loss. Operating temperatures range from -40°C to +100°C. This unshielded filter is part of the RT-Series and serves as a robust solution for electromagnetic interference suppression in high-current applications.

Feature Summary

• Current compensated design for effective common mode noise reduction
• Horizontal PCB mounting configuration for space-efficient integration
• High current handling capability suitable for demanding power stages

Applications

• Embedded systems requiring EMI suppression
• Industrial automation power supplies
• General-purpose EMC filtering in high-current circuits

Procurement Notes

Verify the specific inductance tolerance and physical footprint compatibility before procurement. Confirm that the 63 A current rating aligns with the thermal management capabilities of the target PCB layout. Ensure the through-hole pin diameter matches the manufacturing equipment specifications. Cross-reference the datasheet for any recent packaging or material changes to guarantee supply chain consistency.

Selection Notes

Select this component when high DC current capacity is required alongside significant common mode attenuation. The 500 µH inductance value offers a balance between noise filtering and saturation performance. Consider the unshielded nature of the device regarding spatial constraints and potential magnetic coupling with adjacent components. Evaluate the operating temperature range against the environmental conditions of the final assembly.

Part Context

This component belongs to the RT-Series of common mode chokes manufactured by TE Connectivity / Schaffner. The series is characterized by its robust construction and suitability for high-current applications. The RT8122 model specifically utilizes a ferrite core to achieve the specified inductance values while maintaining low DC resistance. It is distinct from chassis-mounted filters like the FN2000 series, focusing instead on direct PCB integration.
