Common Mode Chokes Procurement Notes

Verify the manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the product family. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure the through-hole package dimensions align with your printed circuit board layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for common mode noise reduction in low-current applications. The 350 mA rating suits portable devices and battery chargers rather than high-power industrial systems. Verify that the 2.6 Ohm DC resistance does not cause excessive voltage drop in your specific circuit design. Consider the physical size constraints of the toroidal package during mechanical integration.

Common Mode Chokes Part Context

This component belongs to the Pulse Electronics common mode choke series designed for electromagnetic interference suppression. It utilizes a toroidal winding technique to minimize external magnetic fields while maximizing inductance density. The product line targets consumer electronics and power conversion equipment requiring reliable noise filtration on AC or DC power lines.
