Hi All. I'm planning a small project using a BC337 transistor.
So my LED requires 130mA and I'm trying to calculate what BASE current I will need. As far as I understand it, required mA divided by tansistor hFE or gain should give me the required mA to switch transistor on.
But when I look at the datasheet for BC337 I see hFE all over the place. Which one do I use?
Have attached the datasheet.
Thanks Guys - JDR04
