In the circuit(it's a Ni-Cd solar charger) below i require a 100uH aircore inductor. Is it ok if I use a readymade inductor(which is not an aircore inductor). Will it affect the circuit in anyway?
Also I did not get a 1N5117 zener diode(it's 400V) why do i require such a high capacity diode for just a 6V application? I got 2, 200V zener diodes. Is it ok if I use them?
Another thing is that the MAX639 IC costed me a whooping 8 US dollars! Why the hell is it so costly??? My allowance(monthly) is only 12dollars(US)!!!
