Abstract
A surface mounting varistor for high voltages and current pulses without any risk of burning a mounting board is provided. A covering material for a varistorhas a duplex (two layer) structure made from a first mold layerand a second mold layer, and a leg with a predetermined height is formed on the bottom of the covering material. As a result, a space (void) formed between a varistor elementand a mounting boardwhen the varistoris mounted on the boardallows avoidance of the risk of burning the board, even if the varistor short-circuits.
