4201-000

Overview

The 4201-000 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes a Pi (LC) circuit topology to provide third-order low-pass filtering for electromagnetic interference suppression. The component features a capacitance value of 1500 pF and supports a maximum DC current of 10 A. It is rated for a voltage of 200 V and operates within a temperature range of 0°C to +125°C. The unit employs UNC-2A threading for secure chassis mounting.

Feature Summary

• Provides high-performance attenuation through a third-order LC Pi-filter topology designed for effective noise reduction in sensitive electronic circuits.

Applications

• Chassis-mounted power line filtering
• Electromagnetic interference suppression in industrial equipment
• Signal integrity protection in communication systems

Procurement Notes

Verify the specific datasheet version for the 4201-000 to confirm RoHS compliance status and exact mechanical dimensions prior to integration. Ensure that the UNC-2A thread specification matches the mounting panel requirements. Confirm thermal derating curves if operation exceeds standard ambient temperatures to maintain reliability under load.

Selection Notes

Select this component when a robust, chassis-mount solution is required for high-current applications up to 10 A. The Pi-filter configuration offers superior attenuation compared to single-capacitor designs. Verify that the 1500 pF capacitance aligns with the target frequency spectrum for noise suppression without affecting signal integrity.

Part Context

This part belongs to the 4201 series of EMI feedthrough filters from Tusonix/CTS. These components are engineered for reliable performance in demanding environments, offering a balance of high current handling and effective noise filtration. The series is commonly used in aerospace, military, and industrial sectors where strict EMC standards apply.

Replacement Considerations

Cross-reference with other UNC-2A threaded Pi-filter models from Tusonix or compatible manufacturers. Ensure substitute parts match the 1500 pF capacitance, 10 A current rating, and 200 V voltage specifications to maintain system compatibility.
