4205-002

Overview

The Tusonix 4205-002 is a third-order low-pass EMI feedthrough filter designed for chassis mounting. It features an axial bushing package with a capacitance of 65 pF and a rated voltage of 125 V. The component supports a maximum DC current of 15 A and operates within a temperature range of -55°C to +125°C. Physical dimensions include a diameter of 0.187 inches, a height of 0.2 inches, and a length of 0.987 inches. It utilizes an 8-32 UNC-2A thread size for secure installation.

Feature Summary

• Third-order Pi filter topology for enhanced high-frequency noise attenuation
• Chassis mount design with integrated bushing for panel integration
• Capable of handling high DC currents up to 15 A

Applications

• Data lines for mobile devices
• Power supply input filtering
• Signal line protection in electronic enclosures

Procurement Notes

Verify the specific suffix (LF vs non-LF) regarding RoHS compliance status before ordering. Confirm that the 8-32 UNC-2A thread specification matches the chassis panel requirements. Ensure the 125 V rating and 15 A current capacity are sufficient for the target circuit conditions. Check lead times as production cycles may vary.

Selection Notes

Select this component when a compact, high-current EMI filter is required for chassis-mounted applications. The 65 pF capacitance offers a balance between noise suppression and signal integrity for data lines. Verify that the physical dimensions fit the available panel space and that the mounting hardware aligns with the specified thread size.

Part Context

This component belongs to the Tusonix 4205 series of EMI feedthrough filters. These components are engineered for robust performance in environments requiring significant noise reduction on power and signal lines. The series is commonly used in industrial and consumer electronics where reliable electromagnetic interference mitigation is critical.

Replacement Considerations

The 4205-002LF serves as the lead-free compliant alternative to the standard 4205-002 variant. Both share identical electrical and mechanical specifications. Ensure the replacement maintains the same thread size and mounting configuration for direct interchangeability.
