Description:

Almost all electronic systems in internal-combustion powered vehicles, e.g., anti-

lock brakes, direct ignition, airbag control, wiper motors, etc. are susceptible to

damage from destructive voltage transients.

Stackpole AVL Series of leaded automotive varistors includes both multilayer and

single layer components, defined by WLD capability. Multilayer devices are intended

WLD applications requiring up to 50 joules of energy, and single layer discs are for

WLD 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 WLD energy

absorption, which MLV devices are incapable of handling.

Features:

•

AC operating voltage range (Vrms) from 14V to 40V

•

DC operating voltage (Vdc) from 16V to 56V

Higher operating voltages are available upon request

•

Power supply voltages (Vdc) 12V, 24V and 42V

•

Broad range of current and energy handling

capabilities realized with either type of construction

•

AVYL high temperature product will have performance

characteristics different from the AVL listed here.
