4201-051

Overview

The 4201-051 is an active EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a Pi-filter circuit topology with a capacitance of 5500 pF and a voltage rating of 200 V. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. Designed for chassis mounting, it utilizes an axial bushing configuration with one turret lead and an 8-32 UNC-2A thread size. The package type is bulk.

Feature Summary

• Provides third-order low-pass filtering via LC (Pi) network topology
• Engineered for high-current applications supporting up to 10 A DC load
• Features robust chassis-mount construction with threaded bushing interface

Applications

• Data lines for mobile devices
• EMI suppression in electronic equipment chassis
• RFI filtering for signal integrity maintenance

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 4201-051LF exist. Confirm that the required thread size matches the 8-32 UNC-2A specification. Ensure the application environment stays within the -55°C to +125°C operating temperature range. Check RoHS compliance requirements against the non-compliant status of standard versions. Validate that the 200 V rating and 10 A current capacity meet system design constraints before procurement.

Selection Notes

Select this component when a third-order low-pass filter is required for chassis-mounted installations. It is suitable for applications demanding high current handling up to 10 A alongside significant capacitance. Consider the axial bushing form factor for panel penetration needs. Compare against other series if different thread sizes or voltage ratings are necessary. Ensure the bulk packaging aligns with assembly line requirements.

Part Context

This part belongs to the 4201 series of EMI feedthrough filters from Tusonix/CTS. The series includes various configurations such as 4201-001LF and 4201-501, differing in capacitance, voltage, and current ratings. These components are designed for robust electromagnetic interference suppression in industrial and commercial electronics.
