4203-501

Overview

The Tusonix 4203-501 is an EMI feedthrough filter with a capacitance of 1500 pF and a voltage rating of 200 V. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. The component features a Pi filter circuit topology and utilizes an 8-32 UNC-2A thread size for mounting. Insertion loss specifications include 60 dB at 20 MHz, 60 dB at 50 MHz, 65 dB at 100 MHz, and 65 dB at 10 GHz.

Feature Summary

• Provides high RF attenuation across multiple frequency bands including 5 MHz, 20 MHz, 50 MHz, 100 MHz, and 10 GHz.
• Utilizes a Pi filter circuit topology for effective electromagnetic interference suppression.
• Features a threaded mounting interface compatible with standard panel installations.

Applications

• Electromagnetic interference filtering in electronic systems
• RF signal attenuation in communication equipment
• Power line filtering for sensitive instrumentation

Procurement Notes

Verify the specific thread size and electrical ratings against your system requirements before ordering. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the mounting hole diameter matches the 8-32 UNC-2A specification for proper installation. Check for any lead-free suffix variations if environmental regulations require it.

Selection Notes

Select this component when a 1500 pF capacitance and 200 V rating are required for EMI suppression. The 10 A current handling capability suits moderate power applications. Consider the Pi filter topology for superior noise rejection compared to single-capacitor designs. Verify that the operating temperature range meets your environmental conditions.

Part Context

This part belongs to the Tusonix 4203 series of EMI feedthrough filters. These components are designed for chassis or panel mounting using threaded interfaces. The series offers various capacitance and voltage options to suit different filtering needs. Tusonix, a subsidiary of CTS Electronic Components, manufactures these filters for industrial and commercial applications.

Replacement Considerations

Direct substitutes must match the 1500 pF capacitance, 200 V rating, 10 A current, and 8-32 UNC-2A thread size. Verify insertion loss characteristics at critical frequencies. Alternative parts from other manufacturers may require mechanical adaptation due to differing thread standards or package dimensions.
