DC Filter Capacitors

Vishay ESTA

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.

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

0.0005 μF to 2 μF. The tolerance is ± 10 %. Other tolerances

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

VOLTAGE RANGE

1000 VDC to 70 000 VDC

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.

Fig. 1

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

Fig. 2

DIELECTRIC RESISTANCE

(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)

Fig. 3

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.

Vishay ESTA DC Filter Capacitors

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

WEIGHT

The approximate weight in grams may be calculated by

multiplying the volume of the capacitor container by

1.2 x 10-3.

TERMINATIONS

Add suffix W to part No. To indicate wire terminations.

CAPACITANCE

Capacitance tolerance of 20 % is standard with those

marked.

DIMENSIONS in millimeters

Notes

(1) Capacitance tolerance of 20 % is standard

• Non standard size containers can be supplied on request
