4251-502

Overview

The 4251-502 is a second-order LC (T-Type) EMI feedthrough filter manufactured by Tusonix. It features a capacitance of 0.022µF and supports a maximum DC current of 10 A. The component utilizes an axial, bushing package with dimensions of D4.8mm diameter by 11.9mm length. Electrical performance includes attenuation values of 10dB at 1MHz and 30dB at 10MHz.

Feature Summary

• Second-order LC T-Type circuit topology for enhanced noise suppression
• Axial leaded bushing package design for panel mounting integration
• Capacitive filtering element rated for 10 A continuous current

Applications

• EMI/RFI noise suppression in electronic equipment power inputs
• Panel-mounted filter installations requiring axial lead termination
• Signal conditioning for circuits sensitive to low-frequency interference

Procurement Notes

Verify the specific datasheet version for the 4251-502 model before procurement, as manufacturer documentation may vary across distributors. Confirm that the axial bushing package dimensions align with your panel cutout requirements. Ensure the 10 A current rating meets the operational load of your application. Cross-reference the 0.022µF capacitance value against your circuit design specifications to guarantee proper filtering characteristics.
