Multilayer High Speed Transient Voltage Surge Suppressor

MHS Varistor Series

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 processes.

Littelfuse Inc. manufactures other Multilayer Varistor Series products,

see the ML, MLE, MLN and AUML series data sheets.
