4202-005

Overview

The 4202-005 is an LC (Pi) topology EMI feedthrough filter manufactured by Tusonix. It features a capacitance of 2500 pF and a rated voltage of 100 V. The component supports a maximum DC current of 30 A and operates within a temperature range of -55°C to +125°C. Physical dimensions are 0.625 inches in length, 0.250 inches in width, and 0.375 inches in height. It utilizes a threaded mounting style with a 12-32 UNEF-2A thread size for secure installation.

Feature Summary

• LC (Pi) filter topology for effective electromagnetic interference suppression
• Threaded mounting configuration for robust mechanical stability
• High current handling capability suitable for power line applications

Applications

• Power supply input filtering
• Electromagnetic compatibility (EMC) mitigation in electronic enclosures
• Signal integrity protection in sensitive instrumentation

Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure compliance with RoHS regulations and lead-free specifications. Confirm that the threaded interface matches the panel cutout dimensions. Validate the rated voltage and current parameters against the actual circuit load conditions before finalizing the procurement order.

Selection Notes

Select this component when a Pi-filter topology is required for high-current power lines. Ensure the 12-32 threaded mount fits the available chassis space. Compare the 2500 pF capacitance value against system noise frequency requirements to confirm adequate attenuation without affecting signal integrity or power delivery performance.

Part Context

This component belongs to the Tusonix 4202 series of EMI feedthrough filters. These components are designed for through-panel mounting and provide significant insertion loss across a broad frequency spectrum. The series offers various capacitance values and voltage ratings to suit different power distribution needs.

Replacement Considerations

Check for equivalent Pi-filter configurations from other manufacturers. Verify that any substitute part maintains the same 12-32 threaded interface and physical footprint to ensure compatibility with existing panel mounts.
