4201-053

Overview

The 4201-053 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a Pi (LC) filter circuit topology with a capacitance of 5500 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 0°C to +125°C. It provides an insertion loss of 65 dB at a test frequency of 100 MHz. The physical dimensions are 23.39 mm in length with a diameter of 4.75 mm, utilizing a metric bushing design for chassis mounting.

Feature Summary

• Integrates a Pi-filter topology combining inductive and capacitive elements for enhanced noise suppression.
• Designed for direct chassis mounting via a metric bushing configuration.
• Capable of handling high continuous DC currents up to 10 Amperes.

Applications

• Chassis-mounted electromagnetic interference filtering
• High-current power line noise suppression
• Industrial equipment EMI mitigation

Procurement Notes

Verify the specific RoHS compliance status as documentation indicates non-compliance. Confirm the exact lead time, which may extend to 32 weeks, against current production schedules. Ensure the metric bushing dimensions align with existing panel cutouts before finalizing procurement orders.

Selection Notes

Select this component when high current capacity and robust mechanical mounting are required. The Pi-filter structure offers superior attenuation compared to simple capacitors. Verify that the 350 V rating and 10 A current limit meet the system's electrical requirements. Consider the physical size constraints due to the chassis-mount bushing design.

Part Context

This part belongs to the Tusonix family of EMI feedthrough filters, specifically designed for robust industrial applications. It utilizes a ceramic or similar dielectric construction typical for high-reliability passives. The manufacturer emphasizes durability and consistent performance in harsh electromagnetic environments.

Replacement Considerations
