MHS Varistor Series

RoHS

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.

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.

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.
