Common Mode Chokes Procurement Notes

Verify the exact suffix designation during procurement, as variations such as 'C' or 'OW' may indicate specific packaging or material configurations defined by the manufacturer. Confirm that the ordered part matches the required 51 µH inductance and 600 mA current rating specifications to ensure compatibility with the target circuit design.

Common Mode Chokes Selection Notes

Select this component when a low-profile, two-line common mode choke is required for signal integrity protection. Ensure the PCB footprint accommodates the 9.5 x 5.65 mm dimensions and that the operating current does not exceed the 600 mA rating. Consider the 160 mΩ DCR impact on signal performance within the specific application context.
