Super Capacitor operation with internal resistance (ESR)
Super Capacitor operation with internal resistance (ESR)
(OP)
When looking at charge and discharge rates for capacitors (super caps in this case), can you model the device as a perfect capacitor with an external resistor equal to the ESR value? Also, I notice that some vendors list a maximum operating current for their super capacitors and others do not. I assume trying to pull current out of them too fast can harm the capacitor. When you're not given a maximum on the specification sheet what would you limit the current to?
