4403-039LF

Overview

The 4403-039LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 100 pF and a rated voltage of 200 V. The component supports a current rating of 10 A and operates within a temperature range of -55°C to +125°C. It utilizes an axial, bushing package with a 4-40 thread specification. The insertion loss is specified as 3 dB at 100 MHz. The physical dimensions are 0.125 inches in diameter by 0.215 inches in length.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough capacitor technology.
• Designed for panel mounting using standard 4-40 threaded connections.
• Capable of handling high current loads up to 10 amperes.

Applications

• Electronic equipment requiring EMI filtering
• Power supply input stages
• Signal line protection

Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure compliance with RoHS standards, as some variants in this series may differ. Confirm that the 4-40 thread size matches the chassis mounting holes. Ensure the 200V rating and 10A current capacity meet the circuit design specifications before procurement.

Selection Notes

Select this component when a low capacitance value of 100 pF is required for high-frequency noise attenuation. The 200V rating makes it suitable for applications where higher voltage tolerance than standard 100V parts is needed. The axial bushing form factor allows for direct panel penetration mounting, simplifying enclosure integration compared to surface mount alternatives.

Part Context

This part belongs to the 4403 series of EMI feedthrough filters from Tusonix. These components are designed to suppress electromagnetic interference in electronic circuits. The series offers various capacitance values and voltage ratings to suit different filtering requirements while maintaining consistent mechanical mounting standards.

Replacement Considerations

The 4403-030LF is a confirmed substitute part number within the same series. Verify that the electrical parameters and mechanical dimensions are compatible with the existing design before replacement.
