The MCR10ERTF1302 is a surface mount varistor (also known as a voltage-dependent resistor or VDR) produced by ROHM Semiconductor. It has a 10mm diameter and is rated to an operating voltage of 130V. The part is made with a thermally enhanced moulded epoxy package, providing superior surge and ESD protection. The MCR10ERTF1302 can absorb transient voltage spikes up to 140V, while maintaining resistance of less than 40 volts. It provides maximum clamping capability up to 1400A, with very low body leakage current. This device is suitable for use in a variety of applications, providing protection from overvoltage, reversals, ESD, and surge events.
