Product introduction:
The gold capacitor monomer (Farad capacitor, supercapacitor) is a capacitor made by using the principle of forming an inductive double charge layer between the active carbon of the electronic conductor and the organic or inorganic electrolyte of the ionic conductor. It has the characteristics of small size, large capacity, good voltage memory characteristics and high reliability. Because of its large capacity, it can store more charges, so it can be used in electronic products, industrial control equipment Backup power supply and auxiliary power supply are used in some products in automobile industry and other fields.

◎ The DC voltage of the constant current/constant voltage source is set to the rated voltage (UR ) .
◎ Set the constant current value of the constant current charging and discharging device specified in Table 1.
◎ Switch the switch S to the DC power supply, and charge it with constant voltage for 30 minutes after the constant current/constant voltage source reaches the rated voltage.
◎ After charging, switch the switch S to a constant current discharge device to discharge with a constant current.
◎ Measure the time t1 and t2 of the voltage across the capacitor from U1 to U2, as shown in Figure 2, and calculate the capacitance value according to the following equation :
