4209-003LF

Overview

The 4209-003LF is a third-order LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF and supports a maximum DC current of 10 A with a voltage rating of 350 V. The component utilizes an axial package with a bushing and one turret lead for mounting. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Third-order LC Pi filter topology for enhanced attenuation
• High voltage rating of 350 V for robust performance
• Axial bushing mount with single turret lead

Applications

• Industrial control systems
• Consumer electronics
• Automotive systems
• IoT devices
• Medical equipment

Procurement Notes

Verify the specific suffix requirements against official datasheets to ensure compliance with environmental standards such as RoHS. Confirm that the axial bushing mounting style aligns with the mechanical design constraints of the target enclosure. Cross-reference the 1500 pF capacitance and 10 A current ratings with circuit specifications to prevent mismatched electrical characteristics during integration.

Selection Notes

Select this component when a third-order low-pass response is required for EMI suppression in high-voltage environments. The 350 V rating and 10 A current capacity make it suitable for power line filtering applications where significant noise reduction is necessary. Ensure the axial bushing form factor fits the available panel or chassis space.

Part Context

This part belongs to the Tusonix EMI feedthrough filter family, designed for effective electromagnetic interference suppression. It complements other axial and pillar-style capacitors in the product line, offering a specialized LC configuration for applications requiring higher order filtering than standard single-capacitor solutions.

Replacement Considerations

Direct substitutes may include other third-order LC filters from Tusonix or compatible manufacturers with matching 1500 pF capacitance, 350 V rating, and 10 A current handling. Verify mechanical compatibility of the axial bushing and turret lead dimensions before substitution.
