Common Mode Chokes Procurement Notes

Verify the specific suffix 'R' against official manufacturer documentation to confirm packaging format, as designations may vary by source. Ensure the part number matches the required 68 uH inductance value precisely. Cross-reference the 3.5 A current rating with system requirements before procurement to avoid saturation issues.

Common Mode Chokes Selection Notes

Select this component when a radial common mode choke with high current handling capability is required. The 68 uH value suits applications needing moderate attenuation at lower frequencies. Verify that the 5.1 mm lead spacing fits the target PCB footprint. Consider the unshielded nature if magnetic coupling with nearby components is a concern.

Common Mode Chokes Part Context

This part is part of the Delevan CM9900R series of common mode chokes. The series offers various inductance values ranging from microhenries to millihenries. All variants share similar physical dimensions and mounting styles but differ in electrical characteristics such as inductance and current ratings.
