4209-003

Overview

The Tusonix 4209-003 is a Pi-filter EMI feedthrough component with 1500 pF capacitance and a 10 A current rating. It operates within a temperature range of -55°C to 125°C. The device utilizes an axial bushing package with one turret lead, designed for chassis mounting. This configuration supports high-frequency noise suppression in electronic systems requiring robust electromagnetic interference filtering.

Feature Summary

• Integrates LC (Pi) filter topology for effective EMI/RFI attenuation
• Features axial bushing construction with a single turret lead for secure panel installation
• Designed for high-current applications with specified thermal stability

Applications

• Chassis-mounted power line filtering
• Industrial equipment EMI suppression
• Military and aerospace electronic systems

Procurement Notes

Verify the specific suffix requirements against official datasheets, as variants like 4209-003LF may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as standard versions may not meet all environmental regulations. Ensure the selected packaging matches your assembly needs, typically bulk for this series.

Selection Notes

Select this component when a Pi-filter topology is required for superior high-frequency attenuation compared to simple capacitors. The 10 A rating suits moderate power applications. Verify that the axial bushing form factor fits the available chassis aperture and that the operating temperature range meets the environmental demands of the target system.

Part Context

This part belongs to the Tusonix 4209 series of metric bushing filters. These components are engineered for high-reliability environments, offering compact footprints with significant filtering capabilities. The series is widely used in sectors demanding strict electromagnetic compatibility standards.

Replacement Considerations

Check for 4209-003LF if lead-free compliance is mandatory. Verify electrical equivalence for capacitance and current ratings before substituting with other Pi-filter models from different manufacturers.
