They are impregnated and filled with a mineral oil. The container is a robust rectangular polypro pylene 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. Note

  • The impregnant used is a non toxic highly purifiedand inhibited mineral oil.

APPLICATIONS

The EPR range is designed specifically for DC applications such as filters:

  • By-pass
  • Coupling
  • Rapid discharge
  • Pulse forming networks
  • R a d a r
  • Laser
  • X-ray equipment 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 0.002 μF to 2 μF. The tolerance is ± 10 %. Other tolerance are available on request. Normal values measured at 1 kHz. 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 indica ted 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) Fig. 3 LIFE EXPECTANCY 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.
