Discharge characteristics
When supercapacitors discharge, the voltage shows a diagonal line. It is important to consider the components of withstand voltage discharge and capacitive discharge when determining the capacity and ESR requirements for application. The withstand voltage component is the most critical in high pulse current applications. In long-term low current applications, the capacitive discharge component is most critical when the voltage drops (t) seconds after discharge at (I) current.
The formula for Vdrop is: Vdrop=I (R+t/c)
When applying supercapacitor pulses, the minimum voltage decreases and low ESR (R value) is used.
When using supercapacitors for low current applications, high capacity (C value) is used.
Due to the inherent internal resistance of supercapacitors, there is a voltage drop during discharge when they are used as backup power sources.
△V=IR
If capacitors are overheated during welding, it will reduce the service life of the capacitors. For example, if a printed circuit board with a thickness of 1.6mm is used, the soldering process should be at 260 ° C for no more than 5 seconds.
After the supercapacitor is soldered, the circuit board needs to be cleaned. Because certain impurities may cause short circuits in capacitors.
When supercapacitors are used in series, there is a problem of individual voltage balance. Simple series connection can cause overvoltage in one or several individual capacitors, resulting in damage to these capacitors and affecting overall performance. Therefore, technical support from manufacturers is required when capacitors are used in series.
