Common Mode Chokes Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm package dimensions and terminal configuration match the target PCB footprint. Check for RoHS compliance status if required by specific regulatory standards. Validate operating temperature range suitability for the intended environment.

Common Mode Chokes Selection Notes

Select this component based on the required 1 mH inductance value and 800 mA current handling capability. Ensure the 310 mOhm DCR meets power loss constraints within the circuit design. Verify that the 5 kOhm impedance at 5 MHz aligns with the targeted noise frequency spectrum. Confirm surface mount compatibility with available assembly equipment.

Common Mode Chokes Part Context

This component belongs to the Ole Wolff Electronics common mode filter choke series, which includes variants such as the OWISFT0905-202 and OWICM1006T-121.
