MLA Automotive Series
MLA Automotive Varistor Series
Description
The MLA Automotive Series 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 Automotive
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 Automotive Series suitable for numerous applications
on power supply, control and signal lines.
The MLA Automotive Series is manufactured from
semiconducting ceramics, and is supplied in a leadless,
surface mount package. The MLA Automtove 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.
