4204-004

Overview

The Tusonix 4204-004 is a third-order LC (Pi) EMI feedthrough filter designed for chassis mounting. It features a capacitance of 5000 pF and supports a maximum DC current of 10 A with a rated voltage of 100 V. The component utilizes an axial bushing package with dimensions of 0.250 inches in diameter by 0.468 inches in length. It provides significant attenuation, achieving 65 dB insertion loss at 100 MHz. The unit operates within a temperature range of -55°C to +125°C.

Feature Summary

• Third-order LC Pi-filter topology for enhanced high-frequency noise suppression
• Chassis mount installation via axial bushing configuration
• High current handling capability suitable for power line applications

Applications

• Mobile device data lines requiring EMI protection
• Power supply input filtering for electronic equipment
• Chassis-mounted interference suppression systems

Procurement Notes

Verify the specific suffix requirements for RoHS compliance when ordering, as non-compliant variants may exist. Confirm that the 100V rating aligns with your system's peak voltage conditions. Ensure mechanical compatibility with the designated chassis aperture for the axial bushing style. Cross-reference the 5000pF capacitance value against your circuit design specifications to prevent signal integrity issues.

Selection Notes

Select this component when high attenuation is required for single-channel power or data lines. The third-order LC architecture offers superior filtering compared to standard first-order capacitors. Consider the physical dimensions and chassis mounting requirements during the layout phase. Evaluate the 10A current rating against the maximum load current to ensure reliable operation under thermal stress.
