There are several kinds of non-polar aluminum electrolytic capacitors.
The basic characteristics of the non-polar electrolytic capacitor have not been changed, but some measures have been taken in the structure, which can be used in reverse.
Whether it can be used in AC circuits and circuits with large ripple current depends on other properties, such as the temperature rise of capacitors, the impedance frequency characteristics of capacitors, etc.

According to different uses, there are many types of non-polar aluminum electrolytic capacitors. The following introduces several small non-polar aluminum electrolytic capacitors with different characteristic levels.

1) Non polar aluminum electrolytic capacitor. Here "general" means that there are no other measures except for the oxide film on both poles.
Its electrical properties are similar to those with polarity, and have the characteristics of small volume and large capacity. The capacitance error, loss tangent, DC leakage current and other indicators are similar to those of ordinary polar electrolytic capacitors. It is mainly used in the polarity conversion of DC or pulse circuit, such as color TV decoding circuit. At present, many manufacturers in China have this kind of capacitor (different series, different electrical performance indicators). 

2) A non-polar aluminum electrolytic capacitor used for frequency division in audio circuits.
This is a special type of non-polar electrolytic capacitor,
it is different from the general non-polar electrolytic capacitor, the volume is slightly larger than the general type, the electrical performance index is also higher than the general type,
the capacitance error is small, the loss is low, and the DC leakage current is small.
As a frequency dividing capacitor, most of them are used at the frequency of 10-20KHZ. The frequency characteristics of wound electrolytic capacitors are also very important.
