Metal-Oxide Varistors (MOVs) Surface Mount Multilayer Varistors (MLVs) > MLA Series MLA Varistor Series 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 Size Table ceramics, and is supplied in a leadless, surface mount package. The MLA Series is compatible with modern Metric EIA reflow and wave soldering procedures. 1005 0402 1608 0603 It can operate over a wider temperature range than Zener diodes, and has a much smaller footprint than plastic- 2012 0805 housed components. 3216 1206 Littelfuse Inc. manufactures other multilayer series 3225 1210 products.
