Surface Mount Varistors
Multilayer Transient Voltage Surge Suppressors
ML Varistor Series
The ML 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 ML 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 ML Series suitable for numerous applications on power supply, control and signal lines. The ML Series is manufactured from semiconducting ceramics, and is supplied in a leadless, surface mount package. The ML 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. 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 for multiline protection and the AUML Series for automotive applications.
Features
