4205-001

Overview

The 4205-001 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes a Pi filter circuit topology to suppress electromagnetic interference. The component features a capacitance of 1500 pF and supports a maximum DC current of 15 A. It has a rated voltage of 125 V and operates within a temperature range of -55°C to +125°C. The physical dimensions are 0.187 inches in diameter by 0.200 inches in length (4.75 mm x 5.08 mm). It employs an UNC-2A thread size for mounting.

Feature Summary

• Pi filter circuit topology for effective noise suppression
• Chassis mount design with threaded interface
• High current handling capability up to 15 A
• Wide operating temperature range suitable for harsh environments

Applications

• Data lines for mobile devices
• Power supply filtering in electronic equipment
• EMI suppression in industrial control systems

Procurement Notes

Verify the specific voltage rating requirement against the datasheet, as variants exist with different ratings. Confirm RoHS compliance status if required for your assembly process. Check lead times as production cycles may vary. Ensure the UNC-2A thread size matches your chassis mounting holes. Validate the 15 A current rating against your circuit's peak load requirements.

Selection Notes

Select this component when a Pi filter configuration is needed for high-current applications. The 1500 pF capacitance offers a balance between filtering performance and signal integrity. Consider the physical size constraints, as the cylindrical package requires specific clearance. Compare with other series like 4251 if higher capacitance or different voltage ratings are necessary for the specific application environment.

Part Context

This part belongs to the 4200 series of EMI feedthrough filters from Tusonix/CTS. These components are designed for robust noise reduction in sensitive electronics. The series includes various capacitance values and voltage ratings to suit different power and data line requirements. The 4205-001 specifically targets applications requiring moderate capacitance with high current capacity.

Replacement Considerations

Check for direct substitutes within the same series with adjusted parameters. Verify compatibility with existing mounting hardware due to the specific UNC-2A thread. Ensure any replacement maintains the 15 A current rating and similar capacitance value to preserve circuit performance.
