CM9900-686

Common Mode Chokes Overview

The CM9900-686 is a PC mount common mode choke manufactured by API Delevan. It features an inductance of 68 mH with a tolerance of 25%. The component has a maximum DC resistance of 0.306 ohms and a rated current of 700 mA. It utilizes a ferrite core and is designed for through-hole mounting with radial leads spaced at 5.1 mm. The physical dimensions are 21.3 mm in length, 18.8 mm in width, and 17 mm in height. It operates within a temperature range of -55°C to +125°C.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for data lines using a ferrite core design.
• Supports through-hole PCB mounting with radial lead configuration.

Common Mode Chokes Applications

• Data line filtering
• Common mode noise suppression

Common Mode Chokes Procurement Notes

Verify the specific suffix (R vs standard) when ordering, as variants may differ in packaging or minor specifications. Confirm RoHS compliance status for the exact batch, as some listings indicate non-compliance while others suggest compliance. Ensure the supplier provides the official datasheet to validate the 68 mH inductance and 700 mA current rating before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component for applications requiring high inductance values in a compact through-hole package. The 68 mH value is suitable for low-frequency noise attenuation. Verify that the 700 mA current rating meets the circuit requirements to prevent saturation. Check compatibility with the 5.1 mm lead spacing for PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to the CM9900 series of PC mount common mode chokes from API Delevan. The series offers various inductance options for different filtering needs. The CM9900-686 specifically targets higher inductance requirements compared to lower-value counterparts in the same form factor.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the CM9900 series with similar inductance and current ratings. Verify mechanical fitment due to the specific 21.3 x 18.8 x 17 mm dimensions and 5.1 mm lead pitch when considering alternatives.
