4400-057

Overview

The Tusonix 4400-057 is a second-order low-pass LC EMI filter designed for axial, bushing mounting. It features a capacitance of 0.05µF and supports a maximum DC current of 10 A with a voltage rating of 200V. The component operates within a temperature range of -55°C to +125°C. Its physical dimensions are 0.156 inches in diameter by 0.340 inches in length (3.97mm x 8.64mm). This feedthrough capacitor provides effective noise suppression in electronic circuits.

Feature Summary

• Second-order low-pass LC filtering architecture
• Axial leaded construction with threaded bushing
• High current handling capability up to 10 A
• Feedthrough design for chassis or panel mounting

Applications

• Power supply input filtering
• Signal line noise suppression
• Chassis-mounted EMI/RFI mitigation

Procurement Notes

Verify the specific suffix requirements for RoHS compliance when ordering, as the base part number may have variations. Confirm the exact thread specification matches your panel cutout requirements. Ensure the 200V rating and 10A current capacity align with your circuit's operational limits before finalizing procurement.

Selection Notes

Select this component when a second-order attenuation response is required for EMI reduction. The axial bushing form factor is suitable for direct panel penetration. Verify that the 0.05µF capacitance value meets your filter cutoff frequency needs. Ensure the mechanical dimensions fit the available space in the enclosure design.

Part Context

This component belongs to the Tusonix 4400 series of feedthrough capacitors. These components are engineered for high-performance electromagnetic interference suppression. The series offers various capacitance values and voltage ratings to suit different application requirements while maintaining consistent mechanical and electrical performance standards.

Replacement Considerations

Publicly confirmed substitute part numbers for the 4400-057 were not identified in the provided documentation. Cross-referencing requires matching the 0.05µF capacitance, 200V rating, 10A current, and axial bushing package specifications.
