Additional Details

The B72220P3681K101 varistor has a maximum surge current rating (Imax) that allows it to absorb significant energy from transient events. The clamping voltage (Vc) of the varistor limits the voltage across the protected circuit, preventing damage to sensitive components. The varistor's energy handling capability (Wmax) is a critical parameter for selecting the appropriate varistor for a given application. The specific values for these parameters can be found in the EPCOS (TDK) datasheet for this part number. It's constructed using a metal oxide ceramic, and its epoxy resin coating is flame-retardant per UL 94 V-0 standards. Its storage temperature ranges from -40 °C to +125 °C.
