Syfer has added to its range of solder-in panel mount EMI filters with a series of discoidal capacitor versions, which offer high capacitance values, up to several microfarads.

The SFSS devices are constructed with a discoidal capacitor soldered to a feedthrough pin.  They are offered with a choice of C0G/NP0 or X7R ceramic dielectrics.

Available in 5 different diameters (2.3mm, 2.8mm, 3mm, 5mm and 8.75mm), capacitance values range from 10pF to an impressive 2.2µF. 

Working voltages range from 50V to 3kV and operating temperature range is -55 to 125 deg C.  These devices are able to withstand a solder-in temperature of 250 deg C. 

The SFSS discoidal series joins the existing SFSR, SFST and SFSU ranges of feedthrough EMI filters for soldering direct to a chassis or panel, suitable for hole diameters of 2.9mm, 3.5mm and 5.8mm respectively. 

Featuring a metal body and epoxy encapsulation, they offer superior filtering performance in a robust package. Working voltages are from 50Vdc to 500Vdc.
