Hi,
What is difference in current limited led and voltage limited led?
As far I know that the resistance of led is constant.
e.g. a led rated with 900mA and 12v.
I observed that the current at 12v is <900mA.
So why they only advise to use current limiter?
Voltage > rated voltage( in this case >12) can also cause damage.
Is current getting increased with increase in temperature for constant voltage?
I have to use smoothing capacitor rated with 1µF.
Aluminum Electrolytic Capacitors
Multilayer Ceramic Capacitors
both are same priced.
Which capacitor will be good?
Thanks
