4403-030

Overview

The 4403-030 is a feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 100 pF with a voltage rating of 200V and a current rating of 10 A. The component utilizes an axial, bushing package with dimensions of 0.125 inches in diameter and 0.215 inches in length (3.18mm x 5.47mm). It operates within a temperature range of -55°C to +125°C and exhibits an insertion loss of 3dB at 100MHz. The unit is equipped with 4-40 thread specifications.

Feature Summary

• Provides effective electromagnetic interference suppression through feedthrough capacitor technology
• Features robust mechanical construction suitable for panel mounting applications
• Maintains stable electrical performance across a wide industrial temperature range

Applications

• Electromagnetic interference filtering in electronic enclosures
• Power supply input/output filtering for sensitive circuits
• Panel-mounted noise reduction in industrial control systems

Procurement Notes

Verify the specific RoHS compliance status as documentation indicates non-compliance for this part number. Confirm that the 4-40 thread specification matches the mounting hardware requirements. Ensure the 200V voltage rating and 10A current capacity are sufficient for the target circuit conditions before finalizing procurement decisions.

Selection Notes

Select this component when axial feedthrough topology is required for direct panel integration. The 100 pF capacitance value targets high-frequency noise attenuation. Verify compatibility with existing chassis threading standards. Consider the physical dimensions to ensure adequate clearance within the designated enclosure space during the design phase.
