4403-680

Overview

The 4403-680 is an axial feed-through capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It provides a capacitance value of 5 pF with a voltage rating of 200 V and a current rating of 10 A. The component operates within a temperature range of -55°C to +125°C. Its physical dimensions are 0.156 inches in diameter by 0.110 inches in length (3.96 mm x 2.79 mm). The device is classified as an EMI feed-through filter designed for surface mount or panel mounting applications.

Feature Summary

• Provides effective electromagnetic interference suppression through integrated feed-through filtering architecture
• Capable of handling high continuous current loads up to 10 amperes
• Maintains stable electrical performance across extreme industrial temperature environments

Applications

• EMI suppression in power distribution systems
• Signal filtering in high-frequency electronic circuits
• Industrial equipment requiring robust noise reduction

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct voltage and capacitance ratings. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants. Check moisture sensitivity level requirements for your assembly process. Ensure the axial bushing package matches your chassis or PCB mounting constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact axial feed-through solution is required for high-current EMI filtering. The 5 pF capacitance offers minimal signal loading while providing significant attenuation for high-frequency noise. Consider the 200 V rating for medium-voltage DC applications. Verify that the 10 A current capacity meets the circuit's operational demands without exceeding thermal limits.
