4402-018

Overview

The Tusonix 4402-018 is an EMI feedthrough filter capacitor designed for axial mounting with a bushing configuration. It features a capacitance of 0.1 µF and a voltage rating of 50 V. The component supports a continuous current of 10 A and provides an insertion loss of 47 dB at 100 MHz. It operates within a temperature range of -55 °C to +125 °C. Physical dimensions include a diameter of 0.156 inches, a length of 0.82 inches, and a height of 0.35 inches. The unit utilizes a 6-32 UNC-2A thread size.

Feature Summary

• Provides high attenuation of electromagnetic interference signals through effective capacitive filtering.
• Supports high continuous current loads up to 10 Amperes without performance degradation.
• Features a robust threaded bushing design for secure mechanical mounting on panel openings.

Applications

• Power supply input filtering for electronic equipment chassis
• EMI suppression in aerospace and military communication systems
• Signal conditioning for high-reliability industrial control panels

Procurement Notes

Verify the specific suffix (LF) against official datasheets to confirm lead-free compliance status. Confirm that the required thread size matches the 6-32 UNC-2A specification for your mounting hardware. Ensure the operating environment stays within the specified -55 °C to +125 °C range to maintain electrical integrity and prevent thermal failure during long-term deployment.

Selection Notes

Select this component when a 50 V rating and 0.1 µF capacitance are required for axial feedthrough applications. The 10 A current capacity makes it suitable for power lines rather than low-current signal paths. Consider the physical dimensions and threaded mounting requirements to ensure compatibility with existing panel cutouts and assembly tools compared to non-threaded alternatives.
