High Voltage DC Filter Capacitors

EC

Vishay ESTA

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 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

0.001 μF to 2 μF. The tolerance is ± 10 %. Other tolerance

are available on request. Normal values measured at 1 kHz.

VOLTAGE RANGE

TEST VOLTAGE

Terminal/terminal (Vt/t)

For DC rating < 20 kV

Vt/t = 2.0 x rated voltage 60 s

For DC rating > 20 kV

Vt/t = 1.5 x rated voltage 60 s
