4403-035LF

Overview

The 4403-035LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 10,000 pF and a rated voltage of 200V at 125°C. The component supports a current rating of 10 A and operates within a temperature range of -55°C to +125°C. It utilizes a threaded 4-40 UNC-2A connection with axial bushing mounting. Physical dimensions include a 0.125-inch diameter and 0.215-inch length. The unit complies with RoHS3 standards and carries an MSL rating of 1.

Feature Summary

• Provides high-capacitance EMI suppression via feedthrough architecture
• Supports robust mechanical installation using standard threaded connections
• Maintains electrical performance across wide industrial temperature extremes

Applications

• Electromagnetic interference filtering in electronic enclosures
• Power line conditioning for sensitive instrumentation
• Signal integrity protection in harsh environmental applications

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm compliance requirements, as non-LF variants may exist within the same series. Confirm that the 4-40 thread specification matches the panel cutout and nut requirements. Ensure the 200V rating aligns with the maximum operating voltage of the target circuit under all thermal conditions.

Selection Notes

Select this component when high capacitance is required for low-frequency noise attenuation in feedthrough configurations. The 4-40 threaded interface necessitates compatible panel mounting hardware. Evaluate the 10 A current handling capability against peak load requirements. Consider the physical envelope constraints imposed by the cylindrical axial form factor during PCB or chassis layout.
