4203-551

Overview

The 4203-551 is a tubular EMI feedthrough filter from the Tusonix 4203 series. It features a capacitance of 5000 pF and a current rating of 10 A. The component utilizes an axial bushing package with a single turret lead for panel mounting. Its physical length is 7.9 mm. This third-order LC filter is designed for high-frequency noise suppression in electronic systems.

Feature Summary

• Third-order LC filtering architecture for enhanced attenuation
• Axial bushing configuration with turret lead for secure panel integration
• Tubular construction optimized for electromagnetic interference suppression

Applications

• Electronic equipment requiring EMI/RFI noise reduction
• Power supply input filtering stages
• Signal line protection against high-frequency interference

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and thermal ratings before finalizing the design. Ensure the mounting hole diameter matches the bushing specifications for proper mechanical fit. Confirm compliance requirements such as RoHS status align with project regulations. Cross-reference the manufacturer part number with distributor listings to ensure authenticity and correct revision level.

Selection Notes

Select this component when a compact, third-order filter solution is required for axial mounting applications. The 10 A current rating suits moderate power applications, while the 5000 pF capacitance provides effective low-pass filtering characteristics. Consider the physical dimensions and lead configuration during PCB or chassis layout planning to ensure adequate clearance and mechanical stability.
