4701-001TLF

Overview

The 4701-001TLF is an LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It functions as a third-order low-pass filter designed for data line applications. The component features an inductance of 0.1 µH and a capacitance of 8200 pF. It supports a maximum current of 10 A and utilizes a square pillar package configuration.

Feature Summary

• Provides broadband noise reduction on supply rails to prevent receiver desense
• Designed to block noise from switching sources in data line applications
• Utilizes LC Pi topology for effective EMI/RFI filtering

Applications

• Data line filtering
• Supply rail noise suppression
• EMI/RFI mitigation in electronic circuits

Procurement Notes

Verify the specific suffix 'TLF' against official manufacturer documentation to confirm surface mount or specific terminal configuration requirements. Confirm RoHS compliance status directly with the supplier, as public records indicate no RoHS information is available for this specific part number variant. Ensure the 10 A current rating aligns with system design constraints before procurement.

Selection Notes

Select this component when a third-order low-pass response is required for high-current data lines. The 0.1 µH inductance and 8200 pF capacitance values define the cutoff frequency characteristics. Consider the square pillar form factor for board space constraints. Validate that the 10 A continuous current capability meets the application's power delivery needs without thermal derating issues.

Part Context

This component belongs to the 4701 series of EMI filters produced by Tusonix. The series includes variants such as 4701-001LF and 4701-001MLF, which share similar electrical parameters but may differ in packaging or termination style. The 4701 series is categorized under passive components specifically for EMI/RFI filtering applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing footprints if considering alternatives within the 4701 series, such as 4701-001MLF, ensuring package dimensions and pin configurations match the design.
