4403-030LF

Overview

The 4403-030LF is an EMI feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a rated voltage of 200V and supports a continuous current of 10A. The component has a capacitance value of 100 pF and operates within a temperature range of -55°C to +125°C. It exhibits an insertion loss of 3dB at 100MHz. The physical package is axial with a bushing configuration, measuring 0.125 inches in diameter and 0.215 inches in length. The unit utilizes a 4-40 thread specification for mounting.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough capacitor technology
• Designed for panel-mounted installation using axial bushing configuration
• Supports high current handling capabilities suitable for power line filtering

Applications

• Electromagnetic interference filtering in electronic equipment
• Power supply input/output noise suppression
• Panel-mounted RF filtering applications

Procurement Notes

Verify the specific suffix requirements for RoHS compliance when ordering, as non-LF variants may exist within the series. Confirm that the 4-40 threaded mounting interface matches the chassis design. Ensure the 200V rating and 10A current capacity align with the circuit specifications. Check lead times as these components are often produced to order rather than held in general stock.

Selection Notes

Select this component when a robust, panel-mount solution for EMI suppression is required. The axial bushing design facilitates direct chassis grounding. Consider the 100 pF capacitance value for high-frequency noise attenuation. Verify thermal stability requirements against the -55°C to +125°C operating range. Compare insertion loss characteristics if specific frequency attenuation profiles are critical for the application.

Part Context

This part belongs to the 4403 series of EMI feedthrough filters from Tusonix/CTS. The series includes various capacitance values and voltage ratings tailored for different filtering needs. These components are widely used in industrial and commercial electronics where reliable noise reduction and durable mechanical mounting are essential for system performance and regulatory compliance.

Replacement Considerations

Check for other parts in the 4403 series with similar electrical parameters. Verify mechanical compatibility regarding the 4-40 thread and overall dimensions before substitution.
