CM9900R-334

Common Mode Chokes Overview

The Delevan CM9900R-334 is a through-hole common mode choke designed for PCB mounting. It features a ferrite core and radial termination with a 5.1 mm lead spacing. The component provides an inductance of 330 µH at a test frequency of 1 kHz, with a tolerance of ±25%. It supports a maximum DC current of 1.7 A and has a maximum DC resistance of 58 mOhms. The unit operates within a temperature range of -55°C to +125°C. Physical dimensions are 18.8 mm in length, 21.3 mm in width, and 17 mm in height. The device is unshielded.

Common Mode Chokes Feature Summary

• Radial through-hole construction for direct PCB integration
• Ferrite core material for effective common mode noise suppression
• Unshielded design suitable for standard electromagnetic environments

Common Mode Chokes Applications

• Power supply input filtering
• Signal line noise reduction
• Electromagnetic interference suppression in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix 'R' against manufacturer documentation to confirm RoHS compliance status, as some sources indicate non-compliance for similar series variants. Confirm package type availability, as bulk and reel options may vary by distributor. Ensure the 5.1 mm lead pitch matches the target PCB footprint. Validate that the 1.7 A current rating meets circuit requirements under maximum operating temperatures.

Common Mode Chokes Selection Notes

Select this component when a 330 µH common mode choke is required for through-hole assembly. The 1.7 A current rating suits moderate power applications. Consider the unshielded nature if space constraints prevent using shielded alternatives. Verify compatibility with soldering processes given the -55°C to +125°C operational range. Compare DCR values against other series parts if voltage drop is critical.

Common Mode Chokes Part Context

This part belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance values while maintaining consistent physical dimensions and mounting styles. The CM9900R designation typically indicates RoHS compliant versions, distinguishing them from the standard CM9900 series which may lack this certification. All units share the same ferrite core technology and radial pin configuration.

Common Mode Chokes Replacement Considerations

Cross-reference with CM9900-334 for non-RoHS equivalents. Check CM9900R-154 or CM9900R-185 for different inductance needs within the same form factor. Verify lead spacing and height compatibility before substitution.
