4201-502

Overview

The 4201-502 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a Pi filter circuit topology with a capacitance of 1000 pF and a maximum DC current rating of 10 A. The component utilizes an axial bushing package with a single turret lead and an 8-32 UNC-2A thread size. Designed for bulk installation, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates a third-order Pi filter circuit for enhanced EMI/RFI suppression
• Utilizes a robust axial bushing construction with a single turret lead
• Supports high current applications up to 10 A DC
• Rated for operation in extreme temperatures from -55°C to +125°C

Applications

• Electronic equipment chassis grounding
• Power supply input filtering
• Signal line noise suppression in industrial systems

Procurement Notes

Verify the specific thread size (8-32 UNC-2A) and lead configuration against panel cutout requirements before integration. Confirm that the 10 A current rating and 1000 pF capacitance align with the target circuit's electrical specifications. Ensure compatibility with the intended mounting method for the axial bushing style.

Selection Notes

Select this component when a compact, high-current EMI solution is required for panel-mounted applications. The Pi filter topology offers superior attenuation compared to simple feedthrough capacitors. Consider the physical dimensions and threading standards to ensure mechanical fit within the enclosure design constraints.

Part Context

This part belongs to the 4201 series of EMI feedthrough filters from Tusonix. These components are engineered for reliable noise reduction in harsh environments. The series provides various capacitance and current ratings to suit different power and signal integrity needs across industrial and commercial electronics.

Replacement Considerations

Direct substitutes include other 8-32 UNC-2A threaded EMI filters with similar 1000 pF capacitance and 10 A ratings. Verify mechanical compatibility and electrical performance equivalence before swapping.
