4101-004LF

Overview

The 4101-004LF is a low-pass LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 1750 pF and a rated voltage of 125 V. The component is designed for solder mount applications with a compact size suitable for dense circuit layouts.

Feature Summary

• Provides effective electromagnetic interference suppression through LC Pi-filter topology
• Designed for direct solder mounting to printed circuit boards
• Low-pass filtering characteristic targets high-frequency noise attenuation

Applications

• General electronic equipment requiring EMI suppression
• Power supply input filtering
• Signal line protection in sensitive circuits

Procurement Notes

Verify the specific capacitance tolerance and leakage current requirements against your design specifications before procurement. Confirm that the 125 V rated voltage aligns with your system's maximum operating conditions. Ensure compatibility with standard soldering processes for surface or through-hole mounting as applicable.

Selection Notes

Select this component when a compact Pi-filter solution is needed for moderate current applications. The 1750 pF capacitance offers a balance between filtering performance and signal integrity for lower frequency noise. Consider thermal management if operating near the upper temperature limits.

Part Context

This part belongs to the 4101 series of EMI feedthrough filters from Tusonix/CTS. These components are engineered for robust noise reduction in electronic systems. The series typically includes various capacitance values to suit different filtering needs while maintaining a consistent form factor for easy integration.

Replacement Considerations

Check for equivalent Pi-filter configurations with similar capacitance and voltage ratings. Verify pinout compatibility and physical dimensions to ensure mechanical fit without redesigning the PCB layout.
