4101-003

Overview

The 4101-003 is a tubular EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It functions as a solder-mount Pi (LC) filter with a capacitance of 1750 pF. The component supports a maximum DC current of 10 A and operates within a temperature range of 0°C to +125°C. It features an axial eyelet package design for panel mounting.

Feature Summary

• Provides third-order low-pass filtering characteristics for effective EMI/RFI suppression
• Utilizes a tubular axial eyelet construction for secure panel integration
• Designed for high-current applications with robust solder mount capabilities

Applications

• Electronic equipment requiring EMI suppression in power lines
• Industrial control systems needing reliable signal integrity
• Military and aerospace electronic assemblies

Procurement Notes

Verify the specific datasheet version for the 4101-003 to confirm exact dimensional tolerances and termination specifications. Ensure compatibility with existing panel cutouts and mounting hardware. Confirm that the 10 A current rating meets the operational requirements of the target circuit without derating issues at elevated temperatures.

Selection Notes

Select this component when a custom capacitance value near 1750 pF is required for LC pi-filter topologies. Consider the axial eyelet form factor if panel mounting is preferred over PCB surface mount alternatives. Evaluate the operating temperature range against the environmental conditions of the final assembly to ensure reliability.

Part Context

This part belongs to the 4101 series of EMI feedthrough filters from Tusonix. These components are designed to attenuate electromagnetic interference in both conductive and radiated forms. The series offers various capacitance values tailored for specific filtering needs while maintaining high current handling capabilities.

Replacement Considerations

Direct substitutes may include other 1750 pF or close-value Pi filters from Tusonix or CTS. Verify mechanical dimensions and thread specifications before substitution.
