4100-003

Overview

The Tusonix 4100-003 is an LC (Pi) EMI feedthrough filter designed for high-current applications. It features a capacitance of 3000 pF and a rated voltage of 125 V, with a maximum DC current handling capability of 15 A. The component utilizes an axial eyelet package configuration, measuring 0.6 inches in length and 0.275 inches in height. Operating within a temperature range of -55°C to +125°C, it serves as a third-order low-pass filter for effective noise suppression.

Feature Summary

• Integrates LC Pi-filter topology for third-order low-pass attenuation
• Supports continuous DC currents up to 15 Amperes
• Features axial eyelet mounting for secure panel integration

Applications

• Power supply input filtering
• DC bus noise suppression
• Industrial control system protection

Procurement Notes

Verify the specific suffix requirements against official datasheets, as non-LF variants may differ in material composition or compliance status. Confirm that the 125V rating aligns with your circuit's peak operating conditions. Ensure mechanical fitment matches the specified axial eyelet dimensions before finalizing procurement orders.

Selection Notes

Select this component when high current capacity is required alongside significant capacitance values. The 125V rating suits moderate voltage DC lines. Compare insertion loss specifications against other series members if higher frequency attenuation is necessary. Verify thermal management capabilities given the 15A current rating and enclosed package design.

Part Context

This part belongs to the Tusonix 4100 series of EMI feedthrough filters. These components are engineered for robust electromagnetic interference suppression in demanding environments. The series offers various capacitance and voltage combinations to suit different power line filtering requirements across industrial and commercial sectors.

Replacement Considerations

Check for 4100-003LF as a potential lead-free alternative. Verify electrical equivalence and physical dimensions before substitution. Consult manufacturer documentation for any functional differences between standard and lead-free versions.
