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

■■Enter disc diameter
*2 Manufacturing range of NVD10UBC is varistor voltages 22…270. *3 NVD14C100 is applied.
Use the varistor within the specified values as there is a risk of destruction of the varistor when the impulse power over the maximum energy is applied.
