SFSW Series EMI Panel-Mount Filters

Knowles Syfer's SFSW series feed-through EMI filters are designed for soldering directly to a chassis or panel and are suitable for hole diameters of 3.5 mm (0.138"). Featuring a metal body and a hermetic seal on one end with epoxy encapsulation on the other, they offer superior filtering performance in a robust package.

The range provides feed-through capacitor filtering to high frequencies, with capacitance values from 10 pF to 33 nF, utilizing ultra-stable C0G or stable X7R dielectric material. Working voltages are from 100 V_DC to 500 V_DC, current rating 5 A, and temperature range -55°C to +125°C with no derating for temperature.

The general range of solder-in EMI filters includes sizes from 2.3 mm to 8.75 mm diameter, with voltages from 50 V to 3 kV. 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 10 pF to 3.3 µF.
