The AUML Series of Multilayer Transient Surge Suppressors
was specifically designed to suppress the destructive
transient voltages found in an automobile. The most common
transient condition results from large inductive energy
discharges. The electronic systems in the automobile, e.g.
antilock brake systems, direct ignition systems, engine
control, airbag control systems, wiper motor controls, etc.,
are susceptible to damage from these voltage transients and
thus require protection. The AUML transient suppressors
have temperature independent suppression characteristics
affording protection from -55ºC to 125ºC.
The AUML suppressor is manufactured from semiconducting
ceramics which offer rugged protection and excellent
transient energy absorption in a small package. The devices
are available in ceramic leadless chip form, eliminating lead
inductance and assuring fast speed of response to transient
surges. These Suppressors require significantly smaller
space and land pads than Silicon TVS diodes, offering greater
circuit board layout flexibility for the designer.

Multilayer Suppressors.
