High Voltage DC Filter Capacitors
TYPE DESCRIPTION
PART NUMBER
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 15 mm 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 successfully 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
0.001 μF to 2 μF. The tolerance is ± 10 %. Other tolerance
are available on request. Normal values measured at 1 kHz.
