MHS Varistor Series
Description
The Multilayer High–Speed MHS Series is a very-low
capacitance extension to the Littelfuse ML family of
transient voltage surge suppression devices available in an
0402 and 0603–size surface mount chip.
Their small size is ideal for high–density printed circuit
boards, being typically applied to protect intergrated
circuits and other sensitive components. They are
particularly well suited to suppress ESD events including
those specified in IEC 61000-4-2 or other standards used
for Electromagnetic Compliance (EMC) testing.

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
reflow and wave soldering prcesses.
Littelfuse Inc. manufactures other multilayer varistor series
products, see the ML, MLE, MLN and AUML Series data
sheets.

MHS Varistor Series
Revision: June 28, 2010
MHS Series
The MHS Series provides protection from ESD and EFT in
high–speed 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.
