Judgment Method of Positive and Negative Electrodes of Electrolytic Capacitor

102 Published by at September 02,2019

Electrolytic capacitors are polar, and they are divided into positive and negative electrodes. Here I will introduce you the method of judging the positive and negative poles.

There are several methods to judge as follows:

1.Appearance discrimination

The first method is to look at the electrolytic capacitor hose, one end of which is marked with a negative electrode. The positive pole at the other end is not indicated.

The second method is to look at the electrolytic capacitor pins. One end of the pin with a grid represents the negative pole, and the other end represents the positive pole.

The guide pin capacitor first looks at the guide pin. The long end of the guide pin is positive, while the short end of the guide pin is negative.

If the electrolytic capacitor positive and negative poles have been cut angle, then the short end of the guide needle will have an electrolytic capacitor positive and negative pole mark.

                                  

2.Measure by instrument

The positive and negative electrolytic capacitors can also be measured by instruments. This requires equipment.

3.The Marking Method of the Circuit Diagram of Electrolytic Capacitor's Positive and Negative Electrodes

In the circuit, one end of the + sign is the positive pole.
