Common Mode Chokes Procurement Notes

Verify the specific package type upon ordering, as sources indicate both reel and bulk packaging options. Confirm the manufacturer's standard delivery period, which may vary. Ensure the order quantity aligns with the supplier's minimum order requirements and multiples. Cross-reference the part number with official datasheets to confirm compatibility with your circuit design before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 150 µH inductance value is required for common mode noise attenuation. Ensure the circuit's maximum DC current does not exceed 2.8 A to prevent saturation or overheating. Verify that the PCB layout accommodates the 5.1 mm lead spacing and the specified physical footprint. Consider the operating temperature range to ensure reliability under your application's thermal conditions.

Common Mode Chokes Part Context

This component belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance values tailored for different filtering needs while maintaining consistent physical dimensions and mounting styles. These components are engineered for robust performance in industrial and commercial electronic applications requiring reliable EMI mitigation.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 150 µH inductance, 2.8 A current rating, and radial through-hole package. Verify equivalent electrical parameters and physical dimensions to ensure board compatibility without redesign.
