4206-001LF

Overview

The 4206-001LF is a Pi filter EMI feedthrough component manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 3000 pF and supports a maximum DC current of 25 A. The rated voltage is 500 V at 125°C, with a maximum DC resistance of 10 GOhms. The unit operates within a temperature range of 0°C to +125°C. Physical dimensions include a diameter of 0.375 inches, a length of 1.31 inches, and a height of 0.687 inches. It utilizes an axial bushing package with two notched leads.

Feature Summary

• Provides electromagnetic interference suppression through LC (Pi) filter topology
• Designed for chassis mounting via axial bushing configuration
• Supports high continuous DC current handling capabilities

Applications

• Chassis-mounted electronic equipment filtering
• Power supply input/output noise reduction
• Industrial control system signal integrity protection

Procurement Notes

Verify the specific suffix requirements against project specifications, as lead times may vary significantly due to manufacturing cycles. Confirm that the axial bushing mounting style aligns with the mechanical design constraints. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the 10 GOhms resistance value with circuit isolation requirements.

Selection Notes

Select this component when a Pi filter topology is required for high-current applications up to 25 A. The 3000 pF capacitance offers specific attenuation characteristics suitable for certain frequency ranges. Consider the physical bulkiness of the 1.31-inch length during PCB or panel layout planning. Evaluate the 500 V rating against peak voltage transients in the target power line environment.

Part Context

This part belongs to the 4206 series of EMI feedthrough filters from Tusonix/CTS. It shares the same Pi filter architecture and 25 A current rating with variants like the 4206-502, which differs primarily in capacitance and voltage ratings. The series is designed for robust chassis mounting applications requiring reliable noise suppression in industrial environments.

Replacement Considerations

The 4206-001 is a non-lead-free variant of this component. Verify if lead-free compliance is mandatory for the end product. Other series members like 4206-502 share the form factor but differ in electrical parameters.
