Surface Mount Varistors
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.
