AV / AVY Series — Automotive Leaded Varistors
Description
Almost all electronic systems in internal-combustion powered vehicles, e.g, anti-lock brakes,
direct ignition, air bag control, wiper motors, etc. are susceptible to damage from destructive
voltage transients.
SEI/KEKO’s AV Series of leaded automotive varistors includes both multilayer and single layer
components, defined by W
LD
capability. Multilayer devices are intended W
LD
applications
requiring up to 50 Joules of energy, and single layer discs are for W
LD
applications requiring
above 50 Joules of energy.
Automotive multilayer varistors offer excellent transient energy absorption due to improved
internal energy distribution. Compared to an equivalent automotive disc varistor, they offer
better electrical characteristic in much smaller size. Automotive disc varistors are specifically
designed and used in applications requiring higher levels of W
LD
energy absorption, which
MLV devices are incapable of handling.
Features
• AC operating voltage (Vrms) from 14V to 35V
• DC operating voltage (Vdc) from 16V to 42V
• Power supply voltages (Vdc) 12V, 24V and 42V
• Broad range of current and energy handling capabilities
realized with either type of construction
• In-line leads on automotive MLV varistors
• MLV varistors: +125°C continuous operating
temperature ( +150°C for AVY )
• W
LD
up to 50J
