4400-073LF

Overview

The 4400-073LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 0.027 µF and a voltage rating of 50V. The component operates within a temperature range of -55°C to +125°C. It utilizes an axial leaded package with bulk packaging.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough capacitor technology
• Designed for high-current applications with a 10 A current rating
• Supports operation in extreme thermal environments ranging from -55°C to +125°C

Applications

• General EMI filtering in electronic circuits
• Power line noise suppression
• Signal integrity protection in sensitive equipment

Procurement Notes

Verify the specific datasheet version for the 4400-073LF to confirm exact dimensional tolerances and thread specifications. Ensure compatibility with existing mounting hardware, as axial feedthrough filters often require specific panel cutouts or threaded inserts. Cross-reference the manufacturer's latest documentation for any updates on material composition or compliance status prior to final design integration.

Selection Notes

Select this component when a low-capacitance feedthrough solution is required for 50V DC or AC lines. The 0.027 µF value offers a balance between noise attenuation and signal transmission for certain frequencies. Consider the axial form factor for direct panel mounting applications where space constraints favor a compact cylindrical profile over larger chassis-mounted alternatives.

Part Context

This part belongs to the 4400 series of EMI feedthrough filters produced by Tusonix/CTS. The series includes various capacitance values and voltage ratings to address different filtering requirements. These components are widely used in industrial, medical, and aerospace electronics for their reliability and compact size.

Replacement Considerations

Direct substitutes may include other 0.027 µF, 50V axial feedthrough capacitors from manufacturers such as Johanson Technology or Vishay, provided mechanical dimensions and current ratings match. Verify that alternative parts meet the same RoHS and REACH compliance standards.
