CMCC1206161ST-CT

Common Mode Chokes Overview

The CMCC1206161ST-CT is a two-line common mode choke manufactured by Venkel, designed for surface mount applications. It features an impedance of 160 Ohms at 100 MHz and supports a current rating of 340 mA. The device exhibits a DC resistance (DCR) of 400 mOhm. Constructed with a horizontal footprint on a four-pad configuration, it operates within standard electronic environments to suppress electromagnetic interference in compact circuit designs.

Common Mode Chokes Feature Summary

• Provides effective noise suppression for two-line signal paths through common mode choke functionality
• Utilizes a horizontal surface mount package design compatible with automated assembly processes
• Maintains low DC resistance to minimize power loss during operation

Common Mode Chokes Applications

• Automotive electronic devices requiring EMI filtering
• Power supply circuits for voltage regulation and conversion
• Portable electronic devices needing compact noise mitigation

Common Mode Chokes Procurement Notes

Verify the specific suffix ST against manufacturer documentation to confirm terminal plating and packaging details. Ensure compatibility with RoHS compliance requirements for your region. Cross-reference the 160 Ohm impedance value at 100 MHz with schematic specifications to confirm suitability for target frequency ranges before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when space constraints require a horizontal SMD form factor for two-line filtering. Evaluate the 340 mA current rating against peak load requirements to prevent saturation. Consider the 400 mOhm DCR impact on signal integrity and power efficiency in low-voltage applications compared to alternative vertical packages.

Common Mode Chokes Part Context

This part belongs to Venkel's CMCC series of common mode chokes, which are engineered for high-density PCB layouts. The series offers various impedance and current ratings tailored for different noise suppression needs. The 1206 case size provides a balance between electrical performance and board real estate utilization for consumer and industrial electronics.

Common Mode Chokes Replacement Considerations

Consult official substitution lists for equivalent impedance and current ratings. Verify mechanical dimensions and pin configurations to ensure fit without PCB redesign. Confirm material composition and environmental ratings match original system requirements.
