4201-055

Overview

The 4201-055 is an EMI/RFI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a third-order LC Pi network topology designed for low-pass filtering applications. The component has a capacitance value of 6000 pF (0.011 µF) and a rated voltage of 100V. It supports a maximum DC current of 10 A and provides an attenuation of 55 dB at 100 MHz. The device utilizes an axial leaded package with a sleeve configuration, suitable for chassis mounting. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Third-order LC Pi network architecture for enhanced high-frequency noise suppression
• Axial leaded construction with sleeve design for secure chassis integration
• Capable of handling 10 A continuous DC current while maintaining signal integrity

Applications

• Data line filtering in mobile devices
• EMI suppression in communication equipment
• Power supply input filtering for sensitive electronics

Procurement Notes

Verify the specific suffix requirements against the manufacturer's datasheet to ensure compliance with RoHS standards, as variations exist within the series. Confirm that the axial sleeve package dimensions match the mechanical constraints of the target chassis mount application. Ensure the 10 A current rating aligns with the operational load to prevent thermal degradation during extended use.

Selection Notes

Select this component when a third-order LC Pi filter is required for high-current data lines. The 6000 pF capacitance offers a balance between filtering effectiveness and signal delay. Consider the axial sleeve package for robust mechanical attachment. Verify that the 100 V rating exceeds the peak operating voltage of the circuit to ensure long-term reliability under varying load conditions.
