4102-000LF

Overview

The 4102-000LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes a Pi filter circuit topology to suppress electromagnetic interference in high-current applications. The component features a capacitance value of 3 nF and a voltage rating of 350 VDC at 85°C. It supports a maximum DC current of 10 A. The physical dimensions include a length of 2.41 inches (61.2 mm) and a diameter of 4.57 mm (0.180 inches). The device is designed for bulk packaging and operates within standard industrial temperature ranges.

Feature Summary

• Pi filter circuit topology for enhanced noise attenuation
• High current handling capability up to 10 A
• Robust construction suitable for panel mounting

Applications

• Power supply input filtering
• Industrial control system noise suppression
• Electromagnetic compatibility (EMC) compliance circuits

Procurement Notes

Verify the specific suffix and RoHS status during procurement, as lead times may vary based on manufacturer stock levels. Confirm that the 350V rating aligns with the peak operating voltage of the target circuit. Ensure mechanical clearance matches the specified 2.41-inch length and 4.57mm diameter for proper panel cutout preparation.

Selection Notes

Select this component when a Pi filter configuration is required for high-current DC lines. The 3 nF capacitance offers a balance between low-frequency attenuation and minimal impact on power delivery. Consider the 350V rating for systems requiring higher voltage margins than standard 100V or 200V feedthrough capacitors provide.

Part Context

This part belongs to the 4102 series of EMI feedthrough filters from Tusonix/CTS. The series is characterized by its ability to handle significant DC currents while providing effective RF noise reduction. It serves as a critical component in maintaining signal integrity in noisy electrical environments.

Replacement Considerations

Direct substitutes must match the 3 nF capacitance, 10 A current rating, and Pi filter topology. Verify that alternative components meet the same 350V DC rating and physical footprint requirements to ensure compatibility with existing panel mounts.
