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 *12mm studs or tinned copper wire.
Note: The impregnant used is a non toxic highly refined,
purified and inhibited mineral oil.
APPLICATIONS
The ET range is specifically designed for high voltage
filters and can be successfully used in the following
applications:
• By-pass
• Coupling
• Filter applications
• X-ray power supplies
• Electrostatic air deaners
TEMPERATURE RANGE
Temperature range is – 55°C to + 85°C. Derating is
required for operation at higher temperatures.
TEMPERATURE COEFFICIENT
Capacitance will increase by 2% per 100°C temperature
rise.
CAPACITANCE RANGE
0.0005µF - 2µF. The tolerance is ± 10%. Other
tolerances are available on request. Nominal values
measured at 1kHz.
VOLTAGE RANGE
1000VDC - 70kVDC
POWER FACTOR
The power factor is variable, and is a function of
temperature and frequency see fig.2. Nominal value
< 0.5% at 20°C
DC Filter Capacitors
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.
DIELECTRIC RESISTANCE
(Parallel resistance) is indicated by the graph of insulance
(MΩ x µF) vs temperature fig.3. The insulance (MΩ x µF)
is nominally 10000s at + 20°C. (Measurements taken
after 1 minute with an applied voltage of 500V)
LIFE EXPECTANCY
ET type capacitors are designed for a life exceptancy of
5000h at 65 °C. To achieve the same life expectancy at
85°C derate to 60% of rated voltage fig.4.
WEIGHT
The approximate weight in grams may be calculated by
multiplying the volume of the capacitor container by 1.2 x
10-3.
