The 10D560K with Varistors 45V 100V 500A Through Hole RoHS is a component manufactured by Hongzhi. It is a varistor designed for 45V to 100V and 500A applications. It is a through-hole component, meaning that it is installed into the board using some kind of mechanical attachment, such as soldering or screwing, and is RoHS certified, meaning that it is compliant with the European Union’s Restriction of Hazardous Substances Directive. This component is designed to protect circuits from over voltages, typically those caused by short duration surges and spikes.
