TYPE ER
Capacitors offer unusually good electrical characteristics,
coupled with very small size. The ER range of capacitors are
manufactured using a mixed dielectric material that consists
of polyester/polypropylene. The container is a rolled
seamed tinplate case that is hermetically sealed. The
construction is designed to prevent internal movement
when subjected to shock and vibration.
Note
• The impregnant used is a non toxic highly refined, purified and
inhibited mineral oil.
APPLICATIONS
The ER range of capacitors are specifically designed for DC
applications.
• Audio coupling
• Pulse forming networks
• Oscillator circuits
• Arc and spark suppression
• RF by-pass
• Tuned filters
• Energy storage
• Integrating circuits
• Low and high pass filters
• High voltage smoothing
Capacitors required for AC applications and high discharge
rates can also be designed from the ER range.
Consult Vishay Electronic GmbH, Division Roederstein
ESTA and Hybrids for your specific requirements.
TEMPERATURE RANGE
Temperature range is - 55 °C to + 85 °C. The nominal
voltage rating is applicable from - 55 °C to + 85 °C.
Derating is required for higher operating temperatures.
TEMPERATURE COEFFICIENT
Capacitance will increase by 2 % per 100 °C temperature
change.
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.

POWER FACTOR
The power factor is variable, and a function of temperature
and frequency. See fig 2. Nominal value < 0.5 % at 20 °C.

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).

LIFE EXPECTANCY
ER 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.
