Surface Mount Multilayer Varistors (MLVs) > AUML Series

Revision: September 14, 2010

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.
