4101-000

Overview

The 4101-000 is a third-order low-pass LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features an axial eyelet package with no leads and utilizes a capacitance value of 1750 pF. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Third-order low-pass filtering topology for enhanced noise attenuation
• Axial eyelet mounting configuration for secure panel installation
• High current handling capability suitable for power line applications

Applications

• Power supply input filtering in electronic equipment
• EMI suppression in industrial control systems
• Signal integrity protection in sensitive instrumentation

Procurement Notes

Verify the specific capacitance tolerance and voltage rating requirements against the official datasheet before procurement. Confirm that the axial eyelet mounting style aligns with the mechanical design constraints of the target application. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the project specifications.

Selection Notes

Select this component when high attenuation at lower frequencies is required alongside significant current carrying capacity. The Pi-filter topology offers superior rejection compared to single-stage filters. Consider the physical dimensions of the axial eyelet package to ensure adequate clearance on the mounting panel during the design phase.

Part Context

This part belongs to the 4101 series of EMI feedthrough filters from Tusonix/CTS. These components are designed for robust electromagnetic interference suppression in demanding environments. The series typically includes various capacitance values and current ratings to suit different power line filtering needs across multiple industries.

Replacement Considerations

Direct substitutes may include other 1750pF LC Pi filters from Tusonix or CTS with compatible current ratings. Verify mechanical compatibility of the eyelet mount and electrical parameters such as insertion loss characteristics before substitution.
