Surface Mount Varistors
Multilayer Transient Voltage Suppressor
MLE Varistor Series
The MLE Series family of Transient Voltage Suppression devices are based
on the Littelfuse Multilayer fabrication technology. These components are
designed to suppress ESD events, including those specified in IEC 61000-
4-2 or other standards used for Electromagnetic Compliance testing. The
MLE Series is typically applied to protect integrated circuits and other
components at the circuit board level operating at 18VDC, or less.
The fabrication method and materials of these devices result in capaci-
tance characteristics suitable for high frequency attenuation/low-pass
filter circuit functions, thereby providing suppression and filtering in a
single device.
The MLE Series is manufactured from semiconducting ceramics and is sup-
plied in a leadless, surface mount package. The MLE Series is compatible
with modern reflow and wave soldering procedures.
Littelfuse Inc. manufactures other Multilayer Series products. See the ML
Series data sheet for higher energy/peak current transient applications. See
the AUML Series for automotive applications and the MLN Quad Array. For
high speed applications see the MHS series.
