Common Mode Chokes Procurement Notes

Verify specific termination requirements when ordering, as suffixes such as LF may indicate lead-free compliance. Confirm that the selected part number aligns with the required inductance value and current handling capabilities for the target application. Ensure compatibility with through-hole assembly processes and verify that the component meets necessary environmental standards for the intended operational temperature range.

Common Mode Chokes Selection Notes

Select this component for applications requiring robust common mode noise reduction in power lines. Consider the 15A current rating and low DCR for efficiency. Verify space constraints for the horizontal cylinder package. Ensure the 100 µH inductance at 10 kHz matches the system's filtering requirements. Check if lead-free specifications are mandatory for the project.
