4701-002MLF

Overview

The 4701-002MLF is a surface mount LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. This third-order low-pass filter integrates an inductance of 0.1µH and a capacitance of 6800pF within a single square pillar package. It supports a current rating of 10 A and operates with high insulation resistance of 10 GOhms. Designed for efficient electromagnetic interference suppression, the component utilizes a compact form factor suitable for dense circuit board layouts while maintaining robust signal filtering capabilities.

Feature Summary

• Integrates LC Pi-filter topology combining inductance and capacitance for third-order low-pass attenuation
• Utilizes a compact square pillar surface mount package design
• Supports high continuous current handling capability

Applications

• Electromagnetic interference suppression in electronic circuits
• RFI noise filtering for signal integrity preservation
• Power line conditioning in compact electronic assemblies

Procurement Notes

Verify the manufacturer designation as Tusonix, a subsidiary of CTS Electronic Components, to ensure authenticity. Confirm the specific electrical parameters including 0.1µH inductance and 6800pF capacitance match system requirements. Check for RoHS compliance documentation and verify the square pillar package dimensions against PCB footprint specifications before integration.

Selection Notes

Select this component when a third-order low-pass response is required in a limited space. The integrated LC structure reduces component count compared to discrete solutions. Ensure the 10 A current rating exceeds the maximum expected load current. Verify that the surface mount square pillar package aligns with available assembly equipment and soldering profiles.

Part Context

This component belongs to the Tusonix family of surface mount EMI filters. It represents a specialized solution for applications requiring significant noise attenuation without occupying excessive board area. The integration of passive components into a single pillar package distinguishes it from standard discrete capacitors or inductors.

Replacement Considerations

Direct substitutes require matching the 0.1µH inductance, 6800pF capacitance, and 10 A current rating. Verify package compatibility for the square pillar surface mount form factor. Consult manufacturer cross-reference lists for equivalent third-order LC filters with identical electrical characteristics.
