AUMOVTM Varistor Series
RoHS
Description
Epoxy Coated
The Littelfuse AUMOVTM Series of low voltage, high surge
current, radial leaded varistors provides an ideal circuit pro-
tection for load dump, jump start voltage transient conditions
specifically for automotive applications.
Phenolic Coated
The maximum peak surge current rating is rated up to 5kA
(8/20 μs pulse) to protect sensitive infotainment systems
from voltage transients. This AEC-Q200 (Table 10) compli-
ant series is available in five disc sizes: 5mm, 7mm, 10mm,
14mm and 20mm; it features a wide VDC voltage range from
16V to 50V.
Features
• Meets the stringent
quality standards of
AEC-Q200 (Table 10)
• Wide operating voltage
range: 14VAC to 42VAC
and 16VDC to 50VDC
