4403-031

Overview

The Tusonix 4403-031 is a miniature EMI feedthrough filter with a capacitance of 500 pF and a rated voltage of 200 V. It supports a continuous current of 10 A and operates within a temperature range of -55°C to +125°C. The component features an axial bushing package with 4-40 thread specifications, measuring 0.156 inches in diameter and 0.340 inches in length. It provides 15 dB insertion loss at 100 MHz.

Feature Summary

• Provides electromagnetic interference suppression through integrated feedthrough capacitor design
• Enables secure panel mounting via threaded axial bushing configuration
• Maintains electrical performance across extended industrial temperature ranges

Applications

• RF filtering in panel-mounted electronic enclosures
• Noise suppression for power and signal lines in military systems
• EMI mitigation in aerospace communication equipment

Procurement Notes

Verify the specific suffix requirements against official datasheets before ordering, as packaging or compliance variations may exist. Confirm that the axial bushing dimensions and thread specifications match the mechanical constraints of the target panel cutout. Ensure the 200 V rating and 10 A current capacity align with the circuit's operational parameters to prevent component failure.

Selection Notes

Select this component when a compact, panel-mount solution is required for high-frequency noise attenuation. The 500 pF value offers a balance between capacitance and self-resonant frequency characteristics suitable for general EMI filtering. Consider the axial form factor for applications requiring direct wire termination or rigid structural integration into chassis panels.
