4204-001LF

Overview

The 4204-001LF is a third-order LC (Pi) low-pass EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance value of 1500 pF and supports a maximum DC current of 10 A. The component is rated for a voltage of 200 V and operates within a temperature range of -55°C to +125°C. Designed for chassis mounting, it utilizes an axial bushing configuration with a single turret lead. The physical dimensions are specified as 0.250 inches in diameter by 0.468 inches in length.

Feature Summary

• Third-order LC Pi topology provides enhanced attenuation characteristics for EMI suppression
• Axial bushing construction with turret lead facilitates secure panel integration
• Low-pass filtering design targets high-frequency noise reduction on power lines

Applications

• Chassis-mounted EMI suppression in electronic enclosures
• Power line filtering for equipment requiring high current handling
• Industrial control systems operating in wide temperature environments

Procurement Notes

Verify the specific voltage rating requirements against the application's peak operational voltages, as datasheets may list varying ratings such as 200V or 350V depending on the source version. Confirm that the axial bushing mounting style aligns with the mechanical design constraints of the target enclosure. Ensure the 10 A current capacity meets the circuit's continuous load demands without exceeding thermal limits.

Selection Notes

Select this component when a third-order attenuation profile is required for effective high-frequency noise elimination. The axial bushing form factor is suitable for direct panel penetration mounting, simplifying assembly compared to surface-mount alternatives. Consider the 1500 pF capacitance value for applications balancing filtering performance with minimal impact on signal integrity or power delivery efficiency.

Part Context

This component belongs to the 4200 series of LC Pi filters from Tusonix/CTS. It shares the same axial bushing package and turret lead configuration as other models in the family, such as the 4204-051LF. The series is designed for robust chassis mounting applications where reliable EMI suppression is critical for system compliance and performance.

Replacement Considerations

Direct substitutes within the same series include the 4204-051LF, which offers higher capacitance but maintains similar mounting and current specifications. Verify compatibility with existing panel cutouts and lead configurations before substitution.
