Any fade with capacitors will be rapid between looking full on and looking off. Now what sort of LED are you fading and what time do you want it to fade over? What voltages have you available to power this LED? Any fade with capacitors will be rapid between looking full on and looking off.
Any fade with capacitors will be rapid between looking full on and looking off. I use the usual 5mm (straw hat?) one, green, 3v, 20mA.
Several tests have been proposed in the literature to determine capacity fading. For example, tests based on electrochemical models, 7,8,9 equivalent circuit models, 10,11,12,13,14 performance-based models, 15,16,17,18 an analytical model with empirical data fitting, 19,20,21,22,23 and statistical methods 24,25,26,27 have been proposed.
Impact of various factors viz. Charge rate (CR), Discharge rate (DR), Total charge exchanged (TCE), Total cycle time (TCT), Ambient Temperature on whole cycling (ATC), Ambient temperature on individual degradation phenomenon (ATD), on capacity fade. Table 2. Literature review of capacity fade studies in batteries
The coefficients are derived from fitting the capacity fading data obtained after performing the 50 experiments for different charge rates, rest periods, and three different ambient temperatures.
FEM simulation is another way to obtain the capacitance with fringing effect considered. But simulation software is not available for everyone and the simulation process may take a long time if an accurate simulation result is wanted. In addition, it’s not easy to add a time varying voltage excitation to the electrode in FEM simulation software.
I suggest you experiment by buying a couple of capacitors, say 100uF and 1000uf, try each one, time the fade time and then determine what actual value you need to suit …
