The SFSU feed-through EMI filters are designed for soldering direct to a chassis or panel, and are suitable for hole diameters of 5.8mm (0.228"). Featuring a metal body and epoxy encapsulation, they offer superior filtering performance in a robust package. The range provides feed-through capacitor filtering to high frequencies, with capacitance values from 10pF to 470nF, utilizing C0G or X7R dielectric material. Working voltages are from 50Vdc to 500Vdc.

The general range of solder-in EMI filters includes sizes from 2.3mm to 8.75mm diameter, with voltages from 50V to 3kV. Supplied either as a "pin and disc" format for low cost and space restricted applications or in metal bodies with epoxy encapsulation. A variety of capacitance values are available from 10pF to 3.3µF.
