CMK-05-T

Common Mode Chokes Overview

The CMK-05-T is a common mode choke manufactured by Cincon Electronics Co. LTD, designed for through-hole PCB mounting within the CMK series. It features a horizontal package with four PC pins and supports a maximum DC current of 20 A. The component exhibits a maximum DC resistance of 7 mOhms and an inductance value of approximately 491 uH. Physical dimensions include a length of 29 mm, width of 25.5 mm, and height of 8 mm. It operates at a test frequency of 10 kHz and complies with RoHS standards.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for power lines
• Supports high current handling up to 20 A
• Features low DC resistance for efficient power transmission

Common Mode Chokes Applications

• Power supply input filtering
• EMI suppression in industrial equipment
• Noise reduction in AC/DC converter circuits

Common Mode Chokes Procurement Notes

Verify the specific inductance tolerance and exact physical height against the official datasheet before integration, as manufacturing revisions may occur. Confirm that the horizontal pin configuration matches the target PCB footprint. Ensure the 20 A current rating aligns with the application's peak load requirements to prevent saturation or thermal issues during operation.

Common Mode Chokes Selection Notes

Select this component when high current capacity and low insertion loss are required for common mode interference mitigation. The horizontal form factor facilitates specific board layout constraints compared to vertical variants. Compare the 491 uH inductance against circuit requirements to ensure adequate attenuation at the target noise frequencies while maintaining the necessary current carrying capability without excessive voltage drop.

Common Mode Chokes Part Context

This component belongs to the CMK series of common mode chokes from Cincon Electronics. It serves as a passive electromagnetic interference filter, distinct from active components or other inductor types like toroids or shielded coils. The series focuses on robust performance for industrial and commercial power applications requiring reliable noise suppression.

Common Mode Chokes Replacement Considerations

The CMK-05-C is a verified substitute within the same series, sharing identical electrical parameters including 20 A current rating and 7 mOhms resistance. Verify mechanical compatibility, specifically the 29 mm x 25.5 mm footprint and pin spacing, to ensure direct interchangeability without PCB redesign.
