Vishay OS-CON
Solid Aluminum Capacitors
with Organic Semiconductor
FREQUENCY CHARACTERISTICS (AT 25 °C)
The greatest feature of the Vishay OS-CON capacitor is its excellent frequency characteristic which is nearly equal to that of a
film capacitor. Using the high conductivity of an organic semiconductor with an electrolyte, and adopting the winding element
for layer thinness of electrolyte, the ESR (Equivalent Series Resistance) is greatly improved, obtaining the frequency
characteristic nearly to the film capacitor.

FREQUENCY (Hz)
The chart above shows the impedance frequency characteristic of Vishay OS-CON, compared to that of other types of
capacitors. The Vishay OS-CON capacitor shows a nearly ideal curve. When compared at 100 kHz of frequency, a Vishay
OS-CON capacitor 47 μF and low impedance aluminum electrolytic capacitor 1000 μF nearly have the same feature. If the
frequency gets higher, the capacitance ratio between the Vishay OS-CON capacitor and aluminum electrolytic capacitor
becomes bigger.

FREQUENCY (Hz)
This chart shows the impedance and ESR frequency characteristics for each size of Vishay OS-CON capacitors. The resonance
point of the Vishay OS-CON capacitor is at 100 kHz to 10 MHz. The ESR becomes about 10 m or less at 100 kHz (829 μF
rating), an extremely small value.

The temperature characteristics of the Vishay OS-CON
capacitor features little changes in temperature for the ESR.
Since ESR is dominant at the high range of impedance (near
resonance point), the ESR value greatly affects noise
clearing capacity. When ESR changes little against the
temperature it means that the noise clearing ability changes
little against temperature as well.
The Vishay OS-CON capacitor is best suited for outdoor
apparatus, vehicles and machinery.

When voltage within rating is applied to the Vishay OS-CON
capacitors (less than 80 % of the rated voltage is
recommended) it shows a stable characteristic where the
capacitance changes little. Also when regarding bias
characteristics, which must be considered in using ceramic
capacitors, the Vishay OS-CON capacitors can be used
safely.

Allowable Ripple Current (100 kHz at + 45 °C)
When selecting a smoothing capacitor for a power supply, the allowable ripple current of the capacitor becomes one of the
standard selections.
The allowable value of the ripple current is decided by the generated heat of the capacitor, but its heating comes out of ESR.
Since a large ESR capacitor generates larger heat value, it can not make the flow of ripple current greater.
The Vishay OS-CON capacitor has a small ESR, and compared to other electrolytic capacitors, can allow far more ripple
currents.
