Littelfuse cheat sheet on all varistors related. Link here (PDF) Transient suppressors can be exposed to high currents for short durations in the nanoseconds to millisecond time frame. Littelfuse Varistors are connected in parallel to the load, and any voltage drop in the leads to the varistor will reduce its effectiveness. Best results are obtained […]

App note: Transient suppression devices and principles
App note from Littlefuse on how do transient suppression devices protect electronic circuits. Link here (PDF) There are two major categories of transient suppressors: a) those that attenuate transients, thus preventing their propagation into the sensitive circuit; and b) those that divert transients away from sensitive loads and so limit the residual voltages. Attenuating a […]
App note: An overview of electromagnetic and lightning induced voltage transients
Application note from Littelfuse on sources of transient voltages that can induced in electronic circuits. Link here (PDF) This Note is an overview of the sources and nature of various transient overvoltages, and the problems that may result. Transients in electrical circuits result from the sudden release of previously stored energy. This energy can be […]
