VCM7122-RC

Overview

The VCM7122-RC is a through-hole common mode choke manufactured by Allied Components International. It features two lines with an inductance of 25.5 mH and a current rating of 4 A. The component has a maximum DC resistance of 0.13 ohms. It is designed for noise suppression applications and complies with RoHS standards, ensuring it is lead-free.

Feature Summary

• Provides effective common mode noise suppression for dual-line circuits
• Constructed with through-hole mounting technology for robust mechanical stability
• Complies with environmental safety standards including RoHS compliance

Applications

• Power supply input filtering
• Data line noise suppression
• EMI reduction in electronic equipment

Procurement Notes

Verify the specific package type and pin configuration against official datasheets before integration. Confirm that the 4 A current rating meets the operational requirements of the target circuit to prevent saturation. Ensure compatibility with the manufacturing process for through-hole components.

Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation. The 4 A rating suits moderate power applications. Consider the physical size constraints for through-hole placement on the PCB. Verify thermal performance under continuous load conditions.

Part Context

This part belongs to the VCM series of common mode chokes from Allied Components International. These components are engineered for general-purpose electromagnetic interference suppression. The series offers various inductance values to suit different filtering needs across consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes with matching inductance and current ratings. Ensure equivalent DC resistance and package dimensions for board compatibility. Verify that alternative parts also meet RoHS requirements if environmental compliance is mandatory.
