RT8122-32-1M5

Overview

The Schaffner RT8122-32-1M5 is a horizontal, two-line common mode choke designed for PCB mounting via through-hole termination. It features a copper core and operates within a temperature range of -40°C to +125°C. Key electrical parameters include an inductance of 1.5 mH with a 1% tolerance, a maximum DC current rating of 32 A, and a maximum DC resistance of 3.4 mOhms. The component supports a maximum operating voltage of 300 VDC and meets UL 94V-0 flammability standards.

Feature Summary

• Horizontal two-line configuration optimized for printed circuit board integration
• Current compensated design utilizing a copper core structure
• High thermal stability suitable for demanding industrial environments

Applications

• Electric vehicle charging stations
• Photovoltaic inverters
• Motor drive systems

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status against the latest TE Connectivity / Schaffner datasheet before finalizing procurement. Confirm that the horizontal mounting orientation and through-hole pin dimensions align with the target PCB layout constraints. Ensure the 32 A current rating and 1.5 mH inductance meet the specific electromagnetic interference suppression requirements of the application circuit.

Selection Notes

Select this component when a high-current, low-resistance common mode filter is required for horizontal PCB assembly. The 1.5 mH inductance provides effective noise attenuation for power lines carrying up to 32 A. Consider the physical footprint and lead diameter specifications during mechanical design. This model is distinct from vertical variants or different inductance values within the RT-Series family.

Part Context

This part belongs to the Schaffner RT-Series, a line of EMC chokes engineered for robust performance in power electronics. The RT8122 variant specifically denotes a two-line horizontal configuration. It is manufactured by TE Connectivity under the Schaffner brand, focusing on solutions for renewable energy and electric mobility sectors where high reliability and thermal management are critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Schaffner models such as those in the RT8121 or RT8522 series only if electrical parameters and mounting orientations match the specific design requirements.
