RIPPLE
The sum of the peak ripple voltage and the DC voltage
should not exceed the rated voltage. Refer to graph fig.1 for
permissible peak-to-peak ripple voltage as a percentage of
rated voltage for various frequencies.

POWER FACTOR
TYPE ET
These capacitors are manufactured using a mixed dielectric
material that consists of polyester/polypropylene film and
capacitor tissue. They are impregnated and filled with a
mineral oil. The container is a Synthetic Resin Bonded Paper
tube sealed at both ends with resin assuring hermetic
sealing. The capacitors are terminated with M5 *12 mm
studs or tinned copper wire.
The power factor is variable, and is a function of temperature
and frequency see fig. 2. Nominal value < 0.5 % at 20 °C

DIELECTRIC RESISTANCE
APPLICATIONS
The ET range is specifically designed for high voltage filters
and can be successfully used in the following
applications:
(Parallel resistance) is indicated by the graph of insulance
(MΩ x μF) vs temperature fig. 3. The insulance (MÉ1 x μF) is
nominally 10 000 s at + 20 °C. (Measurements taken after
1 minute with an applied voltage of 500 V)

CAPACITANCE RANGE
LIFE EXPECTANCY
ET type capacitors are designed for a life exceptancy of
5000 h at 65 °C. To achieve the same life expectancy at
85 °C derate to 60 % of rated voltage fig. 4.
Hours
Temperature range is - 55 °C to + 85 °C. Derating is
required for operation at higher temperatures.
