MLE Varistor Series
Description
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 18V
DC
, or less.
The fabrication method and materials of these devices
result in capacitance 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 supplied 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.
