TYPE EC
The EC range of capacitors are similar in design to the
ET range but are housed in a more robust container.
They 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 (SRBP) tube sealed at both ends with resin
assuring a hermetic seal. The capacitors may be used
in air, oil or SF6. They are terminated with M6 studs x
15mm long or tinned copper wire.
Note: The impregnant used is a non toxic highly purified
and inhibited mineral oil.
APPLICATIONS
The EC range of capacitors are specifically designed for
high voltage filters and can be sucessfully used in the
following applications:
High voltage smoothing
Induction heating
RT transmitter power supplies
X-ray power supplies
TEMPERATURE RANGE
Temperature range is - 40°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
0.001µF - 2µF. The tolerance is ± 10%. Other tolerance
are available on request. Normal values measured at
1kHz.
VOLTAGE RANGE
1000VDC - 100kVDC
TEST VOLTAGE
Terminal/terminal (Vt/t)
For DC rating < 20kV
Vt/t = 2.0 x rated voltage 60s
For DC rating > 20kV
Vt/t = 1.5 x rated voltage 60s
