Film capacitors Humidity-resistant X2 capacitors
X2 capacitors are used not only for EMI suppression. Thanks to their robustness and resistance to humidity and high temperatures, they are also suitable for voltage dividers in capacitive power supplies – for example,those of smart meters that are mounted outside buildings.
A new series of EPCOS X2 interference suppression capacitors offers stable capacitance values even under extremely humid conditions. TheB3292*H/J* series for operating voltages of up to 305 V AC comprises types with rated capacitances ranging from0.1 μF to 15 μF, lead spacings from 15 mm to 37.5 mm and operating temperature ranges from -40 °C to +110 °C. In addition, the capacitors, which employ a metallized polypropylene dielectric (MKP), also feature excellent self-healing properties. These allow weak dielectric areas to be burned out in the event of overvoltages.
Particularly in the case of capacitive power supplies in which the capacitor - in contrast to the interference suppression function - is switched in series with the load (see figure), extremely high demands are made on these components.
