Description
The LNBTVSx-22xx is a dedicated lightning and
electrical overstress surge protection for LNB
voltage regulators in satellite set top box
applications.
This device provides the lightning protection
required to pass the IEC and FCC regulations.
Available in axial, SMB and SMC packages, this
device is compatible with industry standard
mounting processes.
