4202-000LF

Overview

The 4202-000LF is a third-order low-pass LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF and a rated voltage of 350 V at 85°C. The component supports a maximum DC current of 10 A and utilizes an axial bushing package for chassis mounting. Designed for electromagnetic interference suppression, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides third-order low-pass filtering via an LC Pi network topology
• Engineered for high-current applications with a 10 A rating
• Features axial bushing construction for secure chassis mounting

Applications

• Electromagnetic interference suppression in electronic systems
• Power line filtering for sensitive instrumentation
• Chassis-mounted noise reduction in industrial equipment

Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure correct termination and mounting specifications. Confirm that the 350 V rating aligns with your system's peak voltage conditions. Check for RoHS compliance status if required by your assembly standards. Ensure the axial bushing dimensions match your panel cutout requirements before finalizing the order.

Selection Notes

Select this component when a third-order attenuation characteristic is required for effective high-frequency noise rejection. The 10 A current capacity makes it suitable for power distribution lines rather than signal lines. Consider the axial bushing form factor if panel mounting is preferred over PCB integration. Verify that the 1500 pF capacitance value provides adequate filtering without impacting the desired signal bandwidth or power delivery characteristics.

Part Context

This part belongs to the 4202 series of EMI/RFI filters from Tusonix. The series includes various capacitance values and voltage ratings tailored for different power line filtering needs. These components are designed to meet stringent electromagnetic compatibility requirements in demanding environments.

Replacement Considerations

Direct substitutes include other 4202 series variants such as 4202-001LF or 4202-004, provided their capacitance and voltage ratings match the design requirements. Cross-reference mechanical dimensions to ensure compatibility with existing chassis mounts.
