Super capacitor

May 28,2016

    In simple terms, the super capacitor is a very large polarization electrolyte capacitor.The 'big' here refers to the capacity, rather than their physical size.

    Indeed, for ordinary electrolytic capacitor, the capacitance value and/or voltage value, the greater the whole package.Electrolytic capacitor usually offer micro farads orders of magnitude of capacitance values, from about 0.1 uF to about 1 f, the nominal voltage value of up to 1 KVDC.In general, the higher the rated voltage, the smaller capacitance values, and the greater the capacitance value, the greater the encapsulation, and also may reduce working voltage.

   Basically, these rules shall also apply to the super capacitor.Super capacitor capacity values in 1 f, working voltage range from 1.5 V to 160 V or higher.With the increase of capacitance and voltage, the volume will increase.

    Capacitance values around dozens of ferrari's early super capacitance is large, it is mainly used for large power equipment.Small super capacitor with low voltage work ability is commonly used for short-term standby power of consumer electronic equipment.

    Although the super capacitors and electrolytic capacitors there are a lot of similarities, but in the electrical properties and physical size also has a big difference.For example, a common 10 uf, 25 Vdc rated voltage electrolytic capacitor size may be slightly less than or equal to 1 to 10, 2.7 Vdc f f super capacitor.With recent advances in technology, will be increased to 25 super capacitor voltage VDC, size less than one times, according to the specific applications, this volume change might not be significant.
