* Question
| What are the characteristics of electrolytic capacitors? |
* Answer
| (1) The color of the outer casing of the electrolytic capacitor is usually blue, in addition to black, etc., and its shape is usually cylindrical.
(2) It has two pins. In the polar electrolytic capacitor, the two pins have positive and negative poles. The position of the negative polarity pin is marked with a “one” symbol on the housing. (4) The capacity of electrolytic capacitors is generally large, above 1uF (the capacity of some imported electrolytic capacitors is less than this value), and the direct calibration method is adopted. (5) The chip electrolytic capacitor has no long pins. |
