4201-001LF

Overview

The Tusonix 4201-001LF is a third-order LC (Pi) low-pass EMI feedthrough filter designed for single-channel applications. It features a capacitance value of 1500 pF and supports a maximum DC current of 10 A. The component has a voltage rating of 200 V at 85°C and provides an attenuation value of 45 dB at 100 MHz. It utilizes an axial bushing package with one turret lead and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective EMI/RFI suppression through third-order LC Pi-filter topology
• Designed specifically for data line protection in mobile device applications
• Features axial bushing mounting configuration with turret lead termination

Applications

• EMI suppression in mobile device data lines
• Signal integrity protection for electronic circuits
• Chassis-mounted filtering applications requiring bushing installation

Procurement Notes

Verify the specific suffix LF indicates RoHS compliance status against the manufacturer's official documentation, as some series variants may differ. Confirm the exact voltage derating curve at elevated temperatures if operating conditions exceed standard ratings. Ensure the axial bushing mounting style matches the chassis hole specifications before procurement.

Selection Notes

Select this component when a third-order low-pass response is required for high-current data lines. The 10 A current rating and 200 V voltage capability suit robust industrial or automotive environments. Verify that the 1500 pF capacitance aligns with the target frequency attenuation requirements without affecting signal integrity.
