4209-053

Overview

The Tusonix 4209-053 is a third-order LC (Pi) EMI feedthrough filter designed for chassis mounting. It features a capacitance of 5500 pF and a rated voltage of 350 V, with a maximum DC current handling of 10 A. The component utilizes an axial bushing configuration with one turret lead. It provides an insertion loss of 65 dB at a test frequency of 100 MHz. The operating temperature range spans from -55°C to +125°C. Physical dimensions include a diameter of 4.75 mm and a length of 23.39 mm.

Feature Summary

• Third-order LC Pi-filter topology for enhanced attenuation
• High current capacity of 10 A for power line filtering
• Chassis mount design with axial bushing and turret lead
• Wide operational temperature stability

Applications

• Data lines for mobile devices
• Power supply input filtering
• EMI suppression in electronic enclosures

Procurement Notes

Verify the specific datasheet version for the 4209-053 to confirm exact mechanical tolerances and termination details. Ensure compatibility with chassis panel thickness for proper bushing installation. Confirm that the 350 V rating and 10 A current limits meet the circuit requirements. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when high attenuation is required for both power and data lines in mobile device applications. The 5500 pF capacitance offers significant noise reduction compared to lower value units. The 10 A current rating supports higher power applications. Consider the axial bushing form factor for direct panel penetration mounting solutions.

Part Context

This part belongs to the Tusonix EMI Feedthrough Filter series, specifically the metric bushing filter category. It is manufactured by Tusonix, a subsidiary of CTS Electronic Components. The product is classified under electromagnetic interference filters and is distinct from standard axial capacitors due to its integrated shielding and grounding structure.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify electrical parameters such as capacitance, voltage rating, and insertion loss against potential alternatives before substitution.
