4205-500

Overview

The 4205-500 is an LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF and a rated voltage of 125 V. The component supports a maximum DC current of 15 A and operates within a temperature range of -55°C to 125°C. Designed for chassis mounting, it utilizes an axial bushing package with 8-32 UNC-2A threading. This third-order low-pass filter provides effective attenuation for electromagnetic interference in power and signal lines.

Feature Summary

• LC Pi-filter topology for third-order attenuation
• High current handling capability up to 15 A
• Chassis mount design with threaded bushing interface

Applications

• Power line filtering in electronic equipment
• Signal line protection against EMI/RFI
• Chassis-mounted EMC suppression systems

Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as sources indicate 125 V ratings. Confirm the 8-32 UNC-2A thread size matches the installation panel. Check RoHS compliance status if required by project specifications. Ensure the 15 A current rating exceeds the operational load. Validate the axial bushing dimensions for mechanical fit.

Selection Notes

Select this component when high-current EMI filtration is required for chassis-mounted applications. The 1500 pF capacitance offers a balance between filtering performance and leakage current. The 125 V rating suits moderate voltage power lines. Consider the physical size and threading constraints during PCB or panel layout planning.

Part Context

This part belongs to the Tusonix 4205 series of EMI feedthrough filters. These components are designed for robust electromagnetic compatibility in industrial and commercial electronics. The series offers various capacitance and voltage options to suit different circuit requirements while maintaining consistent mechanical mounting standards.

Replacement Considerations

Cross-reference with other 4205 series variants for different capacitance values. Verify equivalent parts from Tusonix or CTS that match the 15 A current and 125 V voltage ratings. Ensure replacement components maintain the same 8-32 UNC-2A threading and axial bushing form factor.
