4203-000LF

Overview

The 4203-000LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes a Pi (LC) circuit topology to provide third-order low-pass filtering characteristics. The component features a capacitance value of 1500 pF and is rated for a maximum voltage of 350 Volts at 85°C. It supports a maximum DC current of 10 A and employs an axial bushing mounting style with turret leads.

Feature Summary

• Provides third-order low-pass filtering via LC Pi topology
• Designed for chassis mounting applications
• Utilizes axial bushing configuration with turret leads

Applications

• Data lines for mobile devices

Procurement Notes

Verify the specific voltage rating context when integrating this component into high-voltage circuits. Confirm that the 350V rating aligns with the operational environment's thermal conditions, as specifications are often temperature-dependent. Ensure mechanical compatibility with the intended chassis aperture and threading requirements before finalizing the design.

Selection Notes

Select this component when third-order attenuation is required for data line protection in mobile device architectures. The 1500 pF capacitance offers a balance between filtering efficacy and signal integrity preservation. Consider the axial bushing form factor for direct panel integration where space constraints favor compact, threaded mounting solutions over surface mount alternatives.
