Varistors Datasheet
AUMOV® Series
Radial Leaded Varistors
RoHS
Description
Silicone Coated
The AUMOV® Varistor Series is designed for automotive
applications requiring load dump, jump start and surge voltage
transient protection.
Phenolic Coated
Features & Benefits
■ Phenolic and Silicone
coating meet the stringent
quality requirements of
AEC-Q200 (Table 10)
■ High energy absorption
particularly for automotive
load dump and jump start
■ Lead–free, Halogen-Free
■ High peak surge current rating
and RoHS compliant
up to 10kA (8/20 μs pulse)
■ Wide operating voltage
range: 14VAC to 625VAC
and 16VDC to 825VDC
■ Five disc sizes available:
5, 7, 10, 14, and 20mm
