4204-051LF

Overview

The 4204-051LF is a third-order LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 5000 pF and a rated voltage of 100 V. The component supports a maximum DC current of 10 A and provides an attenuation value of 65 dB at 100 MHz. Designed for chassis mounting, it utilizes an axial bushing package with one turret lead. The physical dimensions are 0.250 inches in diameter by 0.468 inches in length. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Third-order LC Pi-filter topology for enhanced low-pass filtering performance
• High attenuation capability of 65 dB at 100 MHz
• Robust chassis mounting design with axial bushing configuration

Applications

• Mobile device data lines
• Chassis-mounted EMI suppression systems
• Low-pass filtering in electronic circuits requiring high current handling

Procurement Notes

Verify RoHS3 compliance status as indicated in official documentation. Confirm the specific voltage rating requirements against the 100 V specification. Ensure mechanical compatibility with chassis mounting holes given the axial bushing form factor. Validate thermal operating limits against the -55°C to 125°C range for your specific environment.

Selection Notes

Select this component when a third-order low-pass response is required for EMI reduction. The 10 A current rating suits applications with significant power line currents. The 5000 pF capacitance offers a balance between filtering effectiveness and signal integrity for data lines. Consider the chassis mount style if panel installation is preferred over PCB mounting.

Part Context

This part belongs to the Tusonix 4200 series of EMI/RFI filters. It is distinct from simple feedthrough capacitors like the 4702-005M due to its LC Pi-network structure. The manufacturer, Tusonix, specializes in EMC products under the CTS Electronic Components umbrella. This series targets robust industrial and mobile applications.
