CMCC1206900ST

Common Mode Chokes Overview

The Venkel CMCC1206900ST is a surface-mount common mode choke designed for signal line protection. It features a two-line configuration with an impedance of 90 Ohms at 100 MHz. The component supports a maximum current rating of 370 mA and exhibits a DC resistance (DCR) of 300 mOhm. It operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for high-speed data lines
• Compact 1206 surface mount package suitable for space-constrained designs
• Low DC resistance minimizes signal loss in power or data paths

Common Mode Chokes Applications

• USB interface circuit protection
• High-speed serial communication lines
• Signal integrity enhancement in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -CT) against your bill of materials, as it may indicate tape-and-reel packaging variations. Confirm that the 370mA current rating meets your system's peak requirements. Ensure the 1206 footprint matches your PCB layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when low capacitance and precise impedance matching are required for EMI filtering. The 90 Ohm @ 100 MHz specification targets high-frequency noise attenuation. Consider the 300 mOhm DCR impact on voltage drop if used in power-sensitive applications alongside data lines.

Common Mode Chokes Part Context

This part belongs to Venkel's CMCC series of common mode chokes. It utilizes a multilayer ceramic or ferrite technology typical for SMD filters. The series offers various impedance values and current ratings to suit different signal speeds and power levels in modern electronic assemblies.

Common Mode Chokes Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 90 Ohm impedance at 100 MHz and similar current handling. Verify pin compatibility and thermal characteristics before swapping suppliers.
