4208-000

Overview

The 4208-000 is an EMI/RFI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a Pi-type LC network configuration with a capacitance of 1500 pF. Designed for chassis mounting, the component utilizes an axial package with bushing and two notched leads. The physical dimensions are 0.500 inches in diameter by 0.500 inches in length (12.70mm x 12.70mm). This filter is intended for electromagnetic interference suppression applications requiring robust mechanical integration.

Feature Summary

• Pi-type LC filtering architecture for effective noise attenuation
• Chassis mount design with bushing and notched leads
• Compact axial form factor suitable for panel integration

Applications

• Electromagnetic interference suppression in electronic enclosures
• RFI filtering for power or signal lines entering chassis panels
• Industrial equipment noise mitigation

Procurement Notes

Verify RoHS compliance status as the base part number may differ from lead-free variants like 4208-000LF. Confirm exact lead configuration and bushing specifications against schematic requirements. Ensure chassis hole dimensions match the 0.500-inch diameter specification. Check manufacturer documentation for specific insertion loss curves at target frequencies to validate performance needs.

Selection Notes

Select this component when a Pi-filter topology is required for high-capacitance EMI suppression. The 1500 pF value offers significant filtering capability compared to lower capacitance feedthroughs. Consider the chassis mount style if space constraints prevent through-hole PCB mounting. Verify that the mechanical interface matches available panel cutouts before finalizing the design.

Part Context

This component belongs to the Tusonix family of EMI/RFI filters, specifically within the LC and RC network category. It complements other feedthrough capacitors like the 4702 series by offering active filtering rather than simple capacitance. The product line focuses on robust industrial-grade components for harsh electromagnetic environments.

Replacement Considerations

The 4208-000LF serves as the lead-free compliant alternative to the 4208-000. Verify that the LF variant maintains identical electrical characteristics and mechanical dimensions. No other direct cross-model substitutes are documented in the provided data.
