• Wide operational temperature capability from -55°C to +125°C

Common Mode Chokes Applications

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

Common Mode Chokes Procurement Notes

Verify the specific part number CM9900R-396 against manufacturer documentation to confirm availability and specifications. Check for RoHS compliance status as indicated in official datasheets. Ensure that the required inductance value of 39 mH and current rating of 130 mA align with the circuit design requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required for low-current applications. The 39 mH rating makes it suitable for filtering lower frequency noise compared to lower inductance variants in the CM9900R series. Consider the physical size constraints and the unshielded nature of the device when placing it near sensitive components.

Common Mode Chokes Part Context

This component belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance options ranging from microhenries to millihenries, all sharing similar physical footprints and mounting styles. The CM9900R-396 represents the higher inductance end of the spectrum within this specific package format.

Common Mode Chokes Replacement Considerations

Substitute only with other CM9900R series parts if electrical parameters match exactly. Verify that any alternative maintains the same 39 mH inductance, 130 mA current rating, and 7.19 Ohm DCR to ensure circuit compatibility.
