ML Varistor Series
Description
The ML Series family of transient voltage surge
suppression devices is based on the Littelfuse Multilayer
fabrication technology. These components are designed
to suppress a variety of transient events, including those
specified in IEC 61000-4-2 or other standards used for
Electromagnetic Compliance (EMC). The ML Series is
typically applied to protect integrated circuits and other
components at the circuit board level.
The wide operating voltage and energy range make the ML
Series suitable for numerous applications on power supply,
control and signal lines.
The ML Series is manufactured from semiconducting
ceramics, and is supplied in a leadless, surface mount
package. The ML Series is compatible with modern reflow
and wave soldering procedures.

It can operate over a wider temperature range than Zener
diodes, and has a much smaller footprint than plastic-
housed components.
Littelfuse Inc. manufactures other multilayer series
products. See the MLE Series data sheet for ESD
applications, MHS Series data sheet for high-speed ESD
applications, the MLN Series for multiline protection and
the AUML Series for automotive applications.
