4401-007

Overview

The Tusonix 4401-007 is a feedthrough capacitor designed for electromagnetic interference filtering. It features a capacitance of 1000 pF and a rated voltage of 200 V. The component supports a maximum DC current of 5 A and operates within a temperature range of -55°C to 125°C. It utilizes an axial package with dimensions of 0.156 inches in diameter by 0.110 inches in length (3.96 mm x 2.79 mm). Insertion loss is specified at 20 dB @ 100 MHz.

Feature Summary

• Provides effective electromagnetic interference suppression through high-frequency signal attenuation.
• Supports continuous direct current flow without compromising filtering performance.
• Maintains stable electrical characteristics across extreme environmental temperatures.

Applications

• Power supply input filtering
• Signal line noise reduction
• Electronic equipment chassis grounding

Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to ensure authenticity. Confirm that the axial lead configuration matches the target PCB layout requirements. Check compliance documentation, as this series may not meet all regional RoHS standards depending on the specific manufacturing batch. Validate the thermal rating against the intended operating environment to prevent derating issues during peak load conditions.

Selection Notes

Select this component when a compact axial feedthrough solution is required for low-capacitance applications. Ensure the 200 V rating exceeds the system's peak voltage to maintain safety margins. Consider the 5 A current limit when designing power distribution networks. Verify that the physical dimensions fit within the available enclosure space compared to alternative radial or pill-style capacitors.

Part Context

This component belongs to the Tusonix family of EMI feedthrough filters manufactured by CTS Electronic Components. These devices are engineered for robust noise suppression in sensitive electronic circuits. The axial form factor allows for easy integration into wire-to-board connections or panel-mounted configurations where space constraints dictate a linear footprint.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching capacitance, voltage, current, and physical dimensions with other axial feedthrough capacitors from different manufacturers.
