Abstract: We don\'t expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can\'t solve all issues—each application has different ESD requirements.Knowing that \"one size fits all\" cannot apply to power design, the power designer, or the engineering\"super hero,\" must consider all the potential disruptions to a steady flow of power and thenvarious waysto mitigate them. This tutorial describes voltage- and current-limiting devices and risetime reducers tomanage the power. It also points to free and low-cost software tools to help design lowpass filters, checkcapacitor self-resonance, and simulate circuits.
