To assure reliable operation, transient voltage suppression
should be considered at early stages of the design process.
This can be a complex task as electronic components are
increasingly sensitive to stray electrical transients. The
designer must define the types of transient threats and
determine what applications are needed while meeting the
product agency norms and standards.
Varistors are increasingly used as the front-line solution for
transient surge protection. Littelfuse provides expertise
to the designer and offers the broadest range of circuit
protection technologies to choose from.
Littelfuse varistors are available in a variety of forms to
serve a wide range of applications. Options include ultra
small surface mount multi-layer suppressor (MLV) devices
for small electronics applications, and traditional mid-
range metal-oxide (MOV) radial and axial leaded devices
for protection of small machinery, power sources and
components. Littelfuse also offers larger terminal mount
MOVs for industrial applications.
A more recent innovation to the the Littelfuse product
line, MLVs address a specific part of the transient
voltage spectrum – the circuit board level environment

where, although lower in energy, transients from ESD,
inductive load switching, and even lightning surge
remnants would otherwise reach sensitive integrated
circuits. Each of these events can relate to a product’s
ElectroMagnetic Compatibility (EMC), or its immunity to
transients that could cause damage or malfunction.
Littelfuse offers five distinct versions of MLVs including
the MHS Series ESD Suppressor for high data rates, the
ML Series which supports the broadest application range,
the MLE Series intended for ESD while providing filter
functions, the MLN Series Quad Array in a 1206 & 0805
chip and the AUML Series characterized for the specific
transients found in automotive electronic systems.

Varistor to serve your application.
