Varistor Datasheet
MLA Varistor Series
Surface Mount Multilayer Varistors (MLVs)
RoHS
Description
The MLA 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 MLA
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 MLA
Series suitable for numerous applications on power supply, control
and signal lines.
The MLA Series is manufactured from semiconducting ceramics,
and is supplied in a leadless, surface mount package. The MLA
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.
Additional Information
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.
