The component has an inductance of 47 mH with a tolerance of ±25%. It supports a maximum DC current of 130 mA and exhibits a maximum DC resistance of 7.8 Ohms. Physical dimensions are 18.8 mm in length, 21.3 mm in width, and 17 mm in height, with a lead spacing of 5.1 mm.

Common Mode Chokes Feature Summary

• Radial through-hole construction for PCB mounting
• Ferrite core material for magnetic performance
• Unshielded design configuration

Common Mode Chokes Applications

• Common mode noise suppression in electronic circuits
• Signal integrity filtering in power lines
• EMI reduction in communication interfaces

Common Mode Chokes Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm specific packaging requirements, such as reel quantities, prior to ordering. Ensure the selected variant matches the required inductance and current ratings for the target application circuit design.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required for low-frequency common mode noise attenuation. Consider the 130 mA current limit and 7.8 Ohm DC resistance during thermal and voltage drop analysis. Verify that the unshielded nature does not interfere with nearby sensitive components or trace routing on the PCB layout.

Common Mode Chokes Part Context

This part belongs to the CM9900 series of common mode chokes manufactured by Delevan. The series offers various inductance options tailored for different filtering needs while maintaining consistent physical footprints and mounting styles for design flexibility across product lines.

Common Mode Chokes Replacement Considerations

Cross-reference with other Delevan CM9900 series variants for alternative inductance values. Verify pin compatibility and electrical parameters against competitors before substitution.
