The 14D561K Varistor with 460V to 925V and 4.5KA Through Hole RoHS from Hongzhi is a Transient Voltage Suppression (TVS) device that is designed to provide voltage and current suppression when exposed to electrical transients in a circuit. This component has one or more varistors, or metal oxide varistors (MOVs), which are semiconductor devices that have special non-linear capacitance properties. It has two pins, and once connected in the circuit, it will clamp the voltage at a safe level, usually 15V or less, to protect other components in the circuit from any damage caused by electrical transients. This component is compliant with the Restriction of Hazardous Substances (RoHS) requirements, which restricts the use of hazardous substances in electronic and electrical equipment.
