The B72530G1170K062 with Varistors CT1210K17AUTOG_G manufactured by TDK is a disk-shaped, bidirectional, non-polarized electrical component designed to protect sensitive electronic equipment from high voltage transients. It has an operating voltage of 17V, a capacitance of 1210pF and a dissipation factor of 0.07W. It is constructed of metal-oxide varistor, ceramic base body and a tinned copper wire lead for connection. It is designed to provide protection against fast transients, surges, inductive and capacitive coupling, and noise generated on a dc or low frequency ac line. It is also compliant to the standard for surge protection components, UL1414.
