Common Mode Chokes Procurement Notes

Verify the specific current rating (3.5A vs 4.6A) and DCR values against the official Pulse Electronics datasheet prior to procurement, as sources may vary. Confirm the vertical package orientation and pin configuration match the target PCB layout requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Common Mode Chokes Selection Notes

Select this component when integrated CM/DM filtering is required for data lines. The through-hole format suits applications needing mechanical stability. Verify that the physical footprint (31mm x 24.9mm) fits the design constraints. Compare the 32mOhm DCR against system power loss tolerances to ensure efficiency compliance.

Common Mode Chokes Part Context

This part belongs to the category of data line filters produced by Pulse Electronics Power. It serves as an electromagnetic interference (EMI) suppression solution. The device integrates both common mode and differential mode choke functions into a single housing, simplifying circuit design compared to using separate components for each noise type.
