4400-004

Overview

The Tusonix 4400-004 is an active EMI feedthrough capacitor with a capacitance of 5000 pF and a rated voltage of 100V. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. The component utilizes an axial bushing package with dimensions of 0.157 inches in diameter by 0.276 inches in length (4.00mm x 7.00mm). It features M3x0.5 thread specifications for secure mounting.

Feature Summary

• Provides effective electromagnetic interference suppression through high-frequency signal attenuation
• Supports continuous direct current loads up to 10 Amperes without degradation
• Maintains stable electrical performance across extreme industrial temperature environments

Applications

• Power supply input filtering for sensitive electronic equipment
• EMI suppression in aerospace and defense communication systems

Procurement Notes

Verify the specific datasheet version for the 4400-004 model to confirm exact insertion loss characteristics at target frequencies. Ensure that the mounting interface matches the specified M3x0.5 thread pitch and diameter. Confirm compliance requirements, as this series may not adhere to RoHS standards depending on the manufacturing batch. Validate thermal management strategies for the 10A current rating during operation.

Selection Notes

Select this component when a compact axial feedthrough design is required for 100V circuits carrying moderate DC currents. The 5000 pF value offers a balance between low impedance at high frequencies and minimal impact on power line stability. Consider the physical dimensions against available panel cutouts. Evaluate if the M3x0.5 threading aligns with existing chassis infrastructure before finalizing the design.
