CM9900R-566

Common Mode Chokes Overview

The Delevan CM9900R-566 is a through-hole common mode choke filter designed for PCB mounting. It features an inductance of 56 mH with a tolerance of ±25%, measured at a test frequency of 1 kHz. The component supports a maximum DC current of 130 mA and has a maximum DC resistance (DCR) of 8.69 ohms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 21.3 mm in width, 18.8 mm in length, and 17 mm in height, utilizing radial leads with a 5.1 mm pin spacing.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for two-line circuits using ferrite core technology.
• Designed for reliable operation across a wide industrial temperature range from -55°C to +125°C.
• Features unshielded construction with radial through-hole termination for standard PCB integration.

Common Mode Chokes Applications

• Electromagnetic interference (EMI) filtering in power supply input stages
• Noise suppression in data communication lines requiring common mode rejection
• Industrial control systems operating in high-temperature environments

Common Mode Chokes Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates conflicting information regarding RoHS3 compliance versus non-compliance. Confirm the specific manufacturing batch requirements with the supplier prior to ordering. Ensure that the 130 mA current rating aligns with the application's peak load conditions to prevent saturation or excessive heating during operation.

Common Mode Chokes Selection Notes

Select this component when a high inductance value of 56 mH is required for effective low-frequency noise attenuation. The 8.69 ohm DCR results in significant voltage drop; ensure the circuit can accommodate this loss at the rated 130 mA current. Verify that the physical footprint fits the available PCB space and that the lead spacing matches the board layout.

Common Mode Chokes Part Context

This part belongs to the Delevan CM9900R series of common mode chokes. The series offers various inductance values tailored for different filtering needs while maintaining consistent physical dimensions and mounting styles. The CM9900R-566 specifically targets applications requiring higher inductance compared to lower-value variants in the same family.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 56 mH inductance, 130 mA current rating, and 8.69 ohm DCR specifications. Alternative parts should maintain the same through-hole radial package and 5.1 mm pin spacing to ensure mechanical compatibility without PCB redesign.
