DIELECTRIC PROPERTIES (TYPICAL VALUES)
PET = Polyethylene Terephthalate (Polyester), PP = Polypropylene, PC = Polycarbonate.
DEFINITIONS
The following definitions apply to both film/foil capacitors and
metallized film capacitors.
RATED VOLTAGE (U
The rated voltage is the voltage for which the capacitor is
designed. It is defined as the maximum DC or AC (RMS) volt-
age or the pulse voltage that may continuously be applied to
the terminals of a capacitor up to an operating temperature of
+ 85°C. The rated voltage is dependent upon the property of
the dielectric material, the film thickness and the operating
temperature.
Above + 85°C, but without exceeding the maximum
temperature, the rated voltage has to be derated in
accordance to the dielectric material used. For details, please
refer to the individual data sheets of this catalog.
TEST VOLTAGE OR DIELECTRIC STRENGTH
The test voltage of a capacitor is higher than the rated DC
voltage and may only be applied for a limited time.
The dielectric strength is measured between the electrodes
with a test voltage of 1.6 x U
of 2.0 x U
two seconds.
The occurrence of self-healing or clearing-effects during the
application of the test voltage is permitted for metallized film
capacitors.
AC VOLTAGE
The AC voltage ratings in this catalog refer to clean
sinusoidal voltages without transients. The capacitors in this
catalog must not, therefore, be operated in mains applications
(e.g. across the line). This applies also to capacitors that are
rated with AC voltages ≥ 250 VAC.
Capacitors especially designed for mains operations ( X- and
Y-Capacitors) are listed in our catalog “RFI Suppression Ca-
pacitors”. For operations in the higher frequency range the
applied AC voltage has to be derated. The derated AC volt-
ages are provided in the graphs “Permissible AC Voltage Ver-
sus Frequency” of this catalog.
The calculations of the graphs are based on the assumption
that the temperature rise measured on the surface of the ca-
pacitor under working conditions do not exceed 10°C.
