CMK-04-T

Common Mode Chokes Overview

The CMK-04-T is a common mode choke manufactured by Cincon Electronics Co. LTD, designed for through-hole PCB mounting. It features an inductance of 1.7 mH at 10 kHz and supports a maximum DC current of 3.2 A with a maximum DC resistance (DCR) of 41 mOhm. The component utilizes a vertical package with four pin terminals and exhibits a tolerance of 30%. Its construction includes a lead diameter of 0.6 mm, suitable for standard electronic filtering applications requiring common mode noise suppression.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression through high inductance characteristics
• Supports continuous operation up to 3.2 A maximum DC current
• Utilizes a robust vertical through-hole termination style for secure PCB integration

Common Mode Chokes Applications

• Common mode noise filtering in electronic circuits
• Signal integrity enhancement in data transmission lines
• Power supply input/output noise reduction

Common Mode Chokes Procurement Notes

Verify the specific inductance value of 1.7 mH and the 3.2 A current rating against project requirements. Confirm the 4-pin vertical through-hole package dimensions and 0.6 mm lead diameter for PCB footprint compatibility. Ensure the 30% tolerance aligns with circuit design margins. Cross-reference the manufacturer part number CMK-04-T with official Cincon documentation to validate specifications before procurement.

Common Mode Chokes Selection Notes

Select this component when a 1.7 mH inductance at 10 kHz is required for common mode interference mitigation. The 3.2 A current handling capacity makes it suitable for moderate power applications. The through-hole mounting option is preferred for mechanical stability or legacy board designs. Evaluate the 41 mOhm DCR impact on system efficiency if low-loss performance is critical.

Common Mode Chokes Part Context

The CMK-04-T belongs to Cincon's range of passive magnetic components, specifically common mode chokes. These devices are engineered to attenuate electromagnetic interference (EMI) by blocking high-frequency noise currents while allowing differential signals to pass. The component serves as a critical element in maintaining signal purity and compliance with EMI standards in various electronic assemblies.
