4202-001LF

Overview

The 4202-001LF is a third-order LC (Pi) EMI/RFI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF and a rated voltage of 350 V. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. Designed for chassis installation, it utilizes an axial leaded package with a turret lead configuration. The filter provides significant attenuation, achieving 50 dB insertion loss at 100 MHz.

Feature Summary

• Third-order LC Pi-filter topology for enhanced signal filtering
• Chassis-mount design with axial leads for secure panel integration
• High-voltage rating suitable for demanding power line applications

Applications

• Power line filtering in electronic equipment
• EMI suppression in industrial control systems
• Signal integrity protection in communication hardware

Procurement Notes

Verify the specific RoHS compliance status and datasheet revision before procurement, as documentation sources may vary regarding environmental declarations. Confirm that the 10 A current rating aligns with your system's thermal management capabilities. Ensure chassis mounting provisions match the physical dimensions of the axial turret lead package to guarantee proper mechanical stability during operation.

Selection Notes

Select this component when a third-order low-pass response is required for high-current power lines. The 350 V rating distinguishes it from lower-voltage alternatives in the 4200 series. Consider the axial turret lead format for direct chassis penetration or bracket mounting. Compare against the 4202-004 model if higher capacitance or different voltage ratings are needed for specific circuit requirements.

Part Context

This part belongs to the Tusonix 4200 series of LC Pi filters, designed for robust EMI/RFI suppression. Unlike simple feedthrough capacitors, this component integrates multiple reactive elements to provide steeper roll-off characteristics. It serves as a critical interface between noisy environments and sensitive electronics, ensuring compliance with electromagnetic compatibility standards through effective harmonic attenuation.
