4400-683LF

Overview

The 4400-683LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features an axial bushing package designed for panel mounting applications. The component operates within a temperature range of -55°C to +125°C and has a maximum operating voltage of 200V with a current rating of 10A. The physical dimensions include a diameter of 0.157 inches (approximately 4.00mm). This part belongs to the 4400 series of electromagnetic interference filters.

Feature Summary

• Provides effective electromagnetic interference suppression through feedthrough capacitor technology
• Features an axial bushing configuration suitable for direct panel mounting
• Operates reliably across a wide industrial temperature range from -55°C to +125°C

Applications

• Electromagnetic interference filtering in electronic enclosures
• Power line conditioning for sensitive equipment
• Panel-mounted signal or power line protection

Procurement Notes

Verify the specific capacitance value and detailed insertion loss characteristics against the official manufacturer datasheet before integration, as these critical parameters are not explicitly listed in the provided summary data. Confirm that the axial bushing mechanical interface matches your panel cutout requirements. Ensure the 200V rating and 10A current capacity meet your circuit design specifications. Check for RoHS compliance status variations between manufacturing batches if required by your procurement standards.

Selection Notes

Select this component when a robust, panel-mountable EMI filter is required for axial wiring configurations. The 4400 series offers high reliability for industrial environments due to its extended temperature range. Consider the physical size constraints imposed by the 0.157-inch diameter and ensure adequate clearance for the bushing installation. Compare performance metrics against other feedthrough capacitors if specific frequency attenuation profiles are critical for your application.

Part Context

This component is part of the 4400 series of EMI feedthrough filters produced by Tusonix. The series includes various capacitance values and voltage ratings tailored for different filtering needs. Similar parts in the lineup include the 4400-093 and 4400-039LF, which share the axial bushing form factor but differ in electrical specifications such as voltage and capacitance. These filters are commonly used in aerospace, military, and industrial electronics.

Replacement Considerations

Direct substitutes may include other axial bushing feedthrough capacitors from Tusonix/CTS with matching 200V and 10A ratings. Verify mechanical compatibility with existing panel mounts. Cross-reference with equivalent offerings from other manufacturers ensuring identical footprint and electrical performance.
