4203-050

Overview

The 4203-050 is an LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for chassis mounting, this component features a threaded bushing configuration with axial leads. It operates within a voltage rating of 100V and supports a current capacity of 10A. The filter utilizes a capacitance value of 5000pF to provide attenuation of 65dB at 100MHz. It functions as a third-order low-pass filter suitable for mobile device data lines, operating reliably across a temperature range of -55°C to +125°C.

Feature Summary

• LC Pi topology providing high attenuation for electromagnetic interference suppression
• Chassis mount design with threaded bushing for secure installation
• Capable of handling 10A current load with 100V voltage rating

Applications

• Data line filtering in mobile devices
• EMI suppression in electronic equipment requiring chassis mounting
• Low-pass filtering for signal integrity protection

Procurement Notes

Verify the specific suffix requirements when ordering, as lead times may vary significantly depending on the version selected. Confirm that the non-RoHS compliant status aligns with your project's regulatory constraints before finalizing procurement. Ensure compatibility with existing chassis mounting hardware due to the threaded bushing interface.

Selection Notes

Select this component when high current handling and robust mechanical mounting are required for EMI suppression. The LC Pi topology offers superior attenuation compared to simple capacitors. Consider the physical dimensions and threaded connection type during PCB or panel layout planning to ensure proper fitment within the enclosure.

Part Context

This part belongs to the 4200 series of EMI feedthrough filters from Tusonix/CTS. These components are engineered for applications demanding reliable noise reduction in power and signal lines. The series includes various capacitance values and voltage ratings to suit different circuit requirements while maintaining consistent mechanical form factors.

Replacement Considerations

Check for 4203-050LF as a potential variant. Verify if RoHS compliance is mandatory for your application, as the standard 4203-050 may not meet these regulations. Ensure any substitute maintains the same 5000pF capacitance and 10A current rating.
