Common Mode Chokes Procurement Notes

Verify the specific datasheet version from Signal Transformer or authorized distributors to confirm RoHS compliance status and environmental certifications. Ensure that the 1 A current rating and 150 mOhm DC resistance align with the thermal and electrical requirements of the target circuit design before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a toroidal common mode choke with a 4.25 mH inductance at 1 kHz is required. The 1 A current handling capacity and low DC resistance make it suitable for applications where minimal voltage drop across the filter is critical. Confirm that the through-hole package fits the available PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to the LPTC-V series, which represents an expansion of Signal Transformer's toroidal common mode choke family.
