4204-050

Overview

The 4204-050 is a third-order LC (Pi) EMI filter designed for chassis mounting with an axial bushing configuration. It features a capacitance of 5000 pF and supports a maximum DC current of 10 A at a rated voltage of 100 V. The component provides significant attenuation, achieving 65 dB insertion loss at 100 MHz. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 7.34 mm in diameter by 11.89 mm in length.

Feature Summary

• Third-order low-pass LC Pi-filter topology for enhanced noise suppression
• Chassis-mount design integrating enclosure bonding into filter performance
• Axial bushing construction for secure panel installation

Applications

• Mobile device data line protection
• Chassis-mounted EMI/RFI filtering applications
• Low-frequency signal line noise suppression

Procurement Notes

Verify RoHS compliance status as the standard 4204-050 variant is non-compliant; confirm if lead-free alternatives are required. Ensure chassis mounting provisions allow for low-impedance return path connections to maintain specified performance. Check lead times as the item is supplied on order. Confirm package type matches axial bushing requirements for your enclosure design.

Selection Notes

Select this component when high attenuation at low frequencies is required for data lines. The Pi-filter topology offers superior rejection compared to single-stage feedthrough capacitors. Consider the 10 A current rating and 100 V voltage limit against circuit conditions. The chassis-mount form factor requires adequate panel space and grounding points for optimal RF performance.

Part Context

This part belongs to the Tusonix 4200 series of EMI feedthrough filters. It utilizes LC Pi-filter technology rather than simple capacitive coupling. The axial bushing style distinguishes it from pillar or surface-mount variants in the broader product family. It is specifically engineered for robust mechanical integration into equipment enclosures.

Replacement Considerations

The 4204-050LF is a lead-free compliant alternative within the same series. Verify that substitution maintains identical electrical parameters and mechanical footprint. Ensure the lead-free version meets specific regulatory requirements if RoHS compliance is mandatory for the final assembly.
