I'm going to build a power supply for my tinkering projects using an existing 120/240 VAC to 12/24 VAC transformer rated at 48VA, and will use the 12V option. My week of reading has not answered all of my questions, so I need to ask an expert(s).
The bridge rectifiers I'm looking at on Mouser.com have spade terminals:
Mouser part numbers: 512-GBPC12005 12amp 50v
512-GBPC36005 35amp 50v
512-GBPC35004 35amp 400v
The difference in cost is very small, so would a part with a higher rating be a better choice, considering a larger transformer could be used in the future?
Is current loss a factor in rectifiers, thus making a minimally rated part the only reasonable choice? Are all of these too big?
Reading has suggested a capacitor connected across the DC output of the bridge rectifier for smoothing out the AC ripple. Is this correct, and if so, what size capacitor would be required?
Any advice will be greatly appreciated !!!
Thanks,
DanAir
