Varistor Products Surface Mount Multilayer Varistors (MLVs) > MHS Series RoHS MHS Varistor Series Description The Multilayer HighSpeed MHS Series is a very-low capacitance extension to the Littelfuse ML family of transient voltage surge suppression devices available in an 0402 and 0603size surface mount chip. The MHS Series provides protection from ESD and EFT in highspeed data line and other high frequency applications. The low capacitance of the MHS Series permits usage in analog or digital circuits where it will not attenuate or distort the desired signal or data. Their small size is ideal for highdensity printed circuit boards, being typically applied to protect intergrated Size Table circuits and other sensitive components. They are particularly well suited to suppress ESD events including Metric EIA those specied in IEC 61000-4-2 or other standards used for Electromagnetic Compliance (EMC) testing. 1005 0402 1608 0603 The MHS Series is manufactured from semiconducting ceramics and is supplied in a leadless, surface mount package. The MHS Series is also compatible with modern reow and wave soldering prcesses. Littelfuse Inc. manufactures other multilayer varistor series products, see the ML, MLE, MLN and AUML Series data sheets.
