Panasonic ERZ-CxxEK Block Type Varistors

Panasonic ERZ-CxxEK Block Type Varistors are Type E transient/surge absorbers that are capable of handling larger surge energy than Type D. These Type E varistors serve applications that protect electronic equipment or semiconductors from switching and induced lightning surges. These transient/surge absorbers feature 8000A or 25,0000A maximum peak current and varistor voltage of 200V to 1100V. Panasonic ERZ-CxxEK Block Type Varistors are constructed with UL- and CSA-recognized components and are RoSH compliant.
