4204-051

Overview

The Tusonix 4204-051 is a third-order LC (Pi) low-pass EMI/RFI filter designed for chassis mounting. It features a capacitance of 5000 pF and supports a maximum DC current of 10 A with a voltage rating of 100 V. The component utilizes an axial bushing package with one turret lead, measuring 6.35 mm in diameter and 11.89 mm in length. It provides an attenuation value of 65 dB at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Third-order LC Pi-filter topology for enhanced noise suppression
• Chassis mount installation via axial bushing configuration
• High current handling capability up to 10 A
• Low-pass filtering characteristic for EMI/RFI mitigation

Applications

• Mobile device data lines
• Industrial control systems requiring EMI filtration
• Power supply input stages for sensitive electronics

Procurement Notes

Verify the specific suffix requirements when ordering, as the LF variant indicates RoHS compliance while the base model may differ. Confirm the exact voltage and current ratings against the application schematic to ensure compatibility. Check for availability constraints as this item may be subject to longer standard delivery periods from the manufacturer. Ensure the chassis mounting hole dimensions align with the specified axial bushing size.

Selection Notes

Select this component when high attenuation is required for data lines carrying moderate currents. The third-order LC design offers superior filtering compared to single-stage capacitors. Consider the physical dimensions for chassis integration and verify that the operating temperature range meets environmental demands. Compare with similar Pi-filters if higher current or different capacitance values are needed.

Part Context

This component belongs to the Tusonix 4200 series of EMI feedthrough filters. Tusonix, a subsidiary of CTS Electronic Components, specializes in electromagnetic compatibility products. The 4204-051 is part of their lineup of LC network filters designed for robust industrial and commercial applications where effective noise reduction is critical.

Replacement Considerations

The 4204-051LF is a verified RoHS-compliant substitute for the 4204-051. Verify that the functional specifications remain identical before substitution.
