4106-000LF

Overview

The 4106-000LF is a third-order LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 3000 pF and supports a maximum DC current of 25 A. The component operates within a temperature range of -85°C to +125°C. Designed for axial mounting with eyelet termination, it provides low-pass filtering characteristics suitable for high-current applications requiring significant attenuation.

Feature Summary

• Third-order LC Pi-filter topology for enhanced noise suppression
• High current handling capability up to 25 A
• Wide operating temperature range from -85°C to +125°C
• Axial eyelet termination for secure chassis or panel mounting

Applications

• Power supply input filtering in industrial equipment
• EMI suppression in high-current DC power lines
• Signal conditioning in aerospace and defense systems
• Noise reduction in automotive electronic control units

Procurement Notes

Verify the specific datasheet version for the 4106-000LF to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing mounting hardware due to the axial eyelet design. Check for RoHS compliance status if required by your manufacturing standards. Confirm lead time availability as production cycles may vary. Validate that the 25 A current rating meets your system's peak load requirements without derating issues.

Selection Notes

Select this component when high current capacity and superior attenuation are required compared to standard single-capacitor feedthroughs. The Pi-filter configuration offers better performance than simple capacitors but requires careful PCB or panel layout consideration. Compare against the 4106-001 if higher voltage ratings are needed, though current handling differs. Ensure the axial form factor fits the available space constraints in the enclosure design.

Part Context

This part belongs to the Tusonix 4106 series of LC Pi filters, designed for robust EMI/RFI suppression in demanding environments. Unlike the 4702-005MLF which is a simple capacitor, this unit integrates inductive elements for higher order filtering. It complements the 4204-050LF family but offers different current and capacitance values tailored for specific power line applications.

Replacement Considerations

Direct substitutes include the 4106-000 (non-LF variant) if halogen-free compliance is not strictly enforced. For similar performance, evaluate the 4106-001, noting its distinct capacitance and voltage specifications. Verify mechanical fitment before swapping, as eyelet dimensions may vary slightly between revisions.
