Review on UCTRONICS Values Fast Blow Assorted Plastic by Charles Fowler

This range has many values to try if you are unsure of the current requirements of the circuit in question. This can be very helpful for those trying to understand an unfamiliar design pattern. This is a backup. If it blows you know it has tripped and the current has exceeded the capacity of your chosen or specified overcurrent protection device. In any case, he returned to the drawing board. I'd rather blow a few cheap fuses than risk an expensive, complex, or irreplaceable piece of equipment.
