4400-040

Overview

The Tusonix 4400-040 is an axial feedthrough capacitor with a capacitance of 0.027 µF and a rated voltage of 50 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 an axial bushing package with dimensions of 0.159 inches in diameter and 0.340 inches in length. It utilizes a 4-40 UNC-2A thread specification for mounting.

Feature Summary

• Provides EMI suppression through axial feedthrough architecture
• Supports high continuous DC current handling
• Operates reliably across extended industrial temperature ranges

Applications

• Power supply input filtering
• DC bus line noise reduction
• Industrial control system protection

Procurement Notes

Verify the specific suffix requirements against the manufacturer's official datasheet, as standard packaging may vary. Confirm RoHS compliance status directly with the supplier, as non-LF variants exist within this series. Ensure the mounting interface matches the 4-40 thread specification before procurement to avoid integration issues.

Selection Notes

Select this component when a low-capacitance, high-current feedthrough solution is required for 50 V systems. Compare against the 4400-062LF for higher capacitance needs or the 4400-038LF for higher voltage ratings. Verify that the axial bushing form factor fits the panel thickness and hole size constraints of the target enclosure design.

Part Context

This part belongs to the Tusonix 4400 series of EMI feedthrough filters. The series offers various capacitance values and voltage ratings in a standardized axial bushing format. These components are designed for direct panel mounting to provide effective common-mode noise attenuation in power and signal lines.

Replacement Considerations

The 4400-062 is a similar axial feedthrough filter but offers 0.05 µF capacitance at 50 V. For higher voltage applications, the 4400-038LF provides 10 pF at 200 V. Verify thread compatibility and physical dimensions when substituting.
