4400-089

Overview

The Tusonix 4400-089 is a feedthrough capacitor with a capacitance of 10000 pF (0.01 µF), rated for 50V and 10A current. It features an axial, bushing package measuring 0.157 inches in diameter by 0.276 inches in length (4.00mm x 7.00mm). The component operates within a temperature range of -55°C to +125°C and provides 42dB insertion loss at 100MHz.

Feature Summary

• Provides high attenuation for electromagnetic interference through feedthrough architecture
• Supports continuous DC current loads up to 10 amperes
• Maintains stable electrical performance across extended industrial temperature ranges

Applications

• Power supply input filtering in electronic equipment
• EMI suppression in aerospace wiring harnesses
• Signal line protection in military communication systems

Procurement Notes

Verify the specific voltage and current ratings against your circuit requirements before ordering. Confirm that the axial bushing mounting style matches your panel or chassis design constraints. Ensure compatibility with the required insertion loss specifications for your frequency band. Check for any specific environmental certifications needed for your deployment region.

Selection Notes

Select this component when a compact axial feedthrough solution is required for moderate capacitance values. The 50V rating suits low-voltage power distribution networks. Consider the physical dimensions to ensure adequate clearance within the enclosure. Evaluate the thermal environment to confirm operation within the specified -55°C to +125°C range.

Part Context

This part belongs to the Tusonix 4400 series of EMI feedthrough filters. The series offers various capacitance and voltage combinations in axial and pillar packages. These components are designed for robust noise suppression in demanding environments where space is limited but high reliability is essential.

Replacement Considerations

Consult official substitution lists from CTS Electronic Components for verified equivalents. Cross-reference capacitance, voltage, current, and physical dimensions carefully. Generic replacements may not match the specific insertion loss characteristics or mounting requirements.
