4101-002LF

Overview

The 4101-002LF is a third-order low-pass LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 1750 pF and supports a maximum DC current of 10 A. The component utilizes an axial package with eyelet termination and a single turret lead for mounting. Rated at 100 V, it operates within a temperature range of -55°C to +125°C. The unit measures 0.195 inches in diameter and 0.375 inches in length.

Feature Summary

• Third-order low-pass LC Pi-filter topology for enhanced attenuation
• Axial eyelet configuration with turret lead for secure chassis mounting
• High current handling capability up to 10 A

Applications

• Power line filtering in electronic equipment
• EMI suppression in industrial control systems
• Signal conditioning in communication hardware

Procurement Notes

Verify the specific suffix LF indicates RoHS compliance when sourcing. Confirm that the axial eyelet and turret lead dimensions match the mechanical constraints of the target chassis or panel cutout. Ensure the 10 A current rating aligns with the operational load requirements of the circuit design.

Selection Notes

Select this component when high attenuation is required for power lines carrying significant current. The LC Pi topology offers superior noise rejection compared to simple feedthrough capacitors. Verify that the 1750 pF capacitance does not interfere with signal integrity if used on data lines, as it is primarily designed for power applications.

Part Context

This part belongs to the Tusonix EMI feedthrough filter family, specifically the 4101 series. These components are engineered for robust electromagnetic interference suppression in demanding environments. The manufacturer specializes in custom and standard filters for aerospace, military, and industrial sectors.

Replacement Considerations

Direct substitutes require matching the 1750 pF capacitance, 10 A current rating, and LC Pi topology. Verify mechanical compatibility of the axial eyelet and turret lead configuration. Check for equivalent RoHS compliance status.
