Common Mode Chokes Procurement Notes

Verify the exact part number suffix against manufacturer documentation to ensure correct inductance and package specifications. Confirm that the 1A current rating and 620mOhm DCR meet system requirements. Check for RoHS compliance status if required by assembly standards. Ensure the through-hole footprint matches the PCB design layout before procurement.

Common Mode Chokes Selection Notes

Select this component when a 35 mH common mode choke is required for 1A AC line filtering. Consider the -40°C to 130°C operating temperature range for environmental suitability. Evaluate the 620mOhm DC resistance impact on voltage drop. Verify compatibility with automotive or industrial EPOS environments based on official application lists.

Common Mode Chokes Part Context

This component belongs to the RL-9750 series of through-hole AC line filters from Renco Electronics, Inc., which was acquired by Standex Electronics in 2020. The series includes various inductance values and configurations for custom inductor and choke applications. This specific model is designated for common mode noise reduction in power lines.

Common Mode Chokes Replacement Considerations

Cross-reference with other RL-9750 series variants such as RL-9750-3HL-54.0 or RL-9750-4VM-1-9.8 only if electrical parameters match. Verify pinout and physical dimensions before substitution. No direct substitute part numbers are publicly confirmed for this specific model.
