Hi,
I am fairly new to the electronics world. I just got an internship with an LED company. As a first project my boss wanna run some LED's with an Iout of .5A to 1A using a stepdown transformer of Vin 12VAC. He told me to look into different bridge rectifiers which are SMD. I looked up the electronics website and some of these electrical terms are foreign to me. like Vrrm, If, Iav, Ir, Vdc etc.
I would really appreciate if you could shed some light on decyphering some of these terms
Thanks much

A couple of critical things for any LED are the max current it can operate with and the heat it can dissipate. Of course these are related. THe "f" subscript usually means "forward", so Vf and If are the voltage and current across the LED.

Oh then you must have bright future before you Oh well after I stopped laughing. I came up with this link http://www.allaboutcircuits.com/vol_3/chpt_3/index.html
