The SOCAY 14D180K Varistor is a 14V 36V 1KA Through Hole component with a diameter of 7.5mm and RoHS certification. It is constructed with an element containing two or more non-linear electrical components set to provide a high impedance open circuit and a low impedance short circuit in alternating electrical scenarios. It is designed to be able to protect electrical and electronic equipment from voltage transients, or surge voltage, caused by electrical disturbances such as lightning, power failure, short-circuits, system switching and more. It is typically used in power supplies, load switching, industrial machinery, telecommunication, automobiles and medical equipment.
