4201-053LF

Overview

The 4201-053LF 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 5500 pF and a rated voltage of 200 V at 85°C. The component supports a maximum DC current of 10 A and operates within a temperature range of 0°C to +125°C. It utilizes an 8-32 UNC-2A threaded connection and is supplied in bulk packaging.

Feature Summary

• Pi filter circuit topology for enhanced noise suppression
• Threaded mechanical mounting interface
• High capacitance value for effective EMI filtering

Applications

• Electromagnetic interference suppression in electronic systems
• RFI filtering for power and signal lines
• Industrial equipment noise control

Procurement Notes

Verify the specific voltage rating conditions (200V @ 85°C) against your operational thermal environment. Confirm that the 8-32 UNC-2A thread size matches your panel cutout requirements. Ensure the 10 A current rating exceeds your maximum load current including safety margins. Check RoHS compliance status if required by your assembly specifications.

Selection Notes

Select this component when a Pi filter configuration is required for superior attenuation compared to single-capacitor feedthroughs. The 5500 pF value offers a balance between capacitance and high-frequency performance. The threaded design provides robust mechanical stability for vibration-prone environments. Consider the 0°C to +125°C operating range for industrial applications.

Part Context

This part belongs to the 4201 series of EMI feedthrough filters from Tusonix/CTS. The series includes various capacitance and voltage ratings with standardized threading options. These components are designed for panel-mount installation to provide efficient grounding paths for high-frequency noise currents.
