The B72220P3271K101 is a radial round leaded Metal-oxide Varistor with tinned copper wire terminals and epoxy resin coating. The voltage dependent characteristics enable varistor to protect against high transient voltage spikes. The varistor impedance changes to a low value clamping the transient to a safe level.
Description The C-III Series of Metal-Oxide Varistors (MOVs) are specifically designed for applications requiring high surge energy absorption ratings and superior multiple pulse absorption rating. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types.
