High Voltage DC 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.

TYPE EPR

The EPR range of 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

robust rectangular polypropylene case. The internal

construction is designed to prevent movement when the

capacitor is subjected to mechanical shock or vibration. An

inert welding process ensures hermetic sealing. Standard

terminations are M10 threaded inserts which eliminates the

necessity for large voltage terminals. The case has an

extremely low affinity for moisture and is resistant to virtually

all electrical environments. Brackets can be welded on as

required.

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 10 000 s at + 20 °C. (Measurements taken after 1

minute with an applied voltage of 500 V)

APPLICATIONS

The EPR range is designed specifically for DC

applications such as filters:

LIFE EXPECTANCY

TEMPERATURE RANGE

Temperature range is - 40 °C to + 85 °C. Derating is required

for operation at higher temperatures.

EPR type capacitors are designed for a life exceptancy of

50 000 h at 65 °C. To achieve the same life expectancy at

85 °C derate to 60 % of rated voltage fig. 4.

TEMPERATURE COEFFICIENT

Capacitance will increase by 2 % per 100 °C temperature

rise.

CAPACITANCE RANGE
