Additional Details

The B72520V40M62 varistor's key specifications include a maximum surge current rating (Imax), which indicates its capacity to absorb significant energy from transient events. The clamping voltage (Vc) limits the voltage across the protected circuit, preventing damage to sensitive components. The energy handling capability (Wmax) is a critical parameter for selecting the appropriate varistor for an application. Refer to the EPCOS (TDK) datasheet for specific values related to these parameters. The coating material generally is epoxy resin and conforms to UL 94 V-0 standards. Its storage temperature ranges from -40 °C to +125 °C.
