• Unshielded configuration suitable for standard electromagnetic environments

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• Common mode noise reduction in power supply inputs
• Signal integrity enhancement in communication interfaces

Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various corporate identifiers. Confirm RoHS compliance status directly with the supplier, as documentation indicates potential variations across production batches. Ensure the ordering quantity aligns with the minimum order requirements specified by the distributor, typically involving bulk packaging units. Cross-reference the part number against official datasheets to confirm electrical parameters match the application requirements before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 330 µH inductance value is required for common mode noise attenuation in low-to-medium current applications up to 1.7 A. The radial through-hole package facilitates manual assembly or wave soldering processes. Consider the physical dimensions and lead spacing to ensure compatibility with the printed circuit board layout. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions.

Common Mode Chokes Part Context

The CM9900 series comprises common mode chokes manufactured by Delevan, now part of API Technologies. These components are engineered for robust performance in filtering applications. The series offers various inductance values to accommodate different noise suppression needs while maintaining consistent physical footprints for standardized PCB designs.

Common Mode Chokes Replacement Considerations

Direct substitutes include other Delevan CM9900 series variants with matching inductance and current ratings. Verify that alternative components maintain the same radial lead spacing and physical dimensions to ensure mechanical compatibility without requiring PCB layout modifications.
