4253-002

Overview

The 4253-002 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It utilizes LC (Pi) topology to provide third-order low-pass filtering characteristics. The component features a capacitance value of 0.05µF and supports a continuous current rating of 10 A. It operates within a voltage range up to 70V and is housed in an axial bushing package with dimensions of 0.250 inches in diameter and 0.807 inches in length.

Feature Summary

• Provides effective attenuation of electromagnetic interference through LC Pi network architecture
• Supports high continuous current handling for power line applications
• Designed for panel mounting via axial bushing configuration

Applications

• Power supply input filtering
• Electronic equipment chassis grounding points
• Industrial control system noise suppression

Procurement Notes

Verify the specific manufacturer designation as Tusonix or CTS Electronic Components during sourcing, as both names appear in distributor listings. Confirm RoHS compliance status directly with the supplier, as available data indicates varying or unspecified regulatory classifications for this part number across different channels.

Selection Notes

Select this component when a robust, high-current EMI solution is required for panel-mounted installations. Ensure the circuit voltage does not exceed the 70V rating and that the physical dimensions fit the designated chassis aperture. Consider the axial bushing form factor for direct wire termination needs.

Part Context

This component belongs to the 4253 series of tubular EMI filters. It is distinct from other Tusonix/CTS feedthrough capacitors like the 4306 series due to its integrated LC structure rather than simple capacitance. The series is designed for harsh environments requiring reliable noise reduction in power lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering any alternative components from different manufacturers.
