FEATURES
Varistors own two-way symmetries and can absorb positive and
negative surges
Able to withstand high current and high energy handling capability
Wide operating voltage range
Ideal for use as countermeasure for inductive lightning surges of
equipment which is connected to DC and AC lines
Absorption of surge voltages from inductive load of motors, relays etc.
and protection of semiconductor elements from excessive voltage
Flame retardant epoxy resin overcoating (UL94 V-0)
Products (82V or over) of this series are recognized
by UL1449 (File No. E79023)
Products (200V or over) of this series are recognized
by UL1414 (File No. E123805)
Storage temperature range: -40°C…+125°C
Operating temperature range: -40°C…+85°C
