We see from your search that you're looking for information on the term "Voltage spikes",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Fanless computer suits signage applications from
BVM, which we summarised at the time by saying "The WPC-763 is configured to accept the barcode scanners, photo sensors, card readers, limit switches, printer and other peripherals required in POS and kiosk applications".
A few weeks before,
we featured the news release How not to let your electrical system catch cold from
Powervar: "Rob Morris argues that power systems - like computers - need to be protected from viruses".
In August 2007, we covered the news from Fairchild Semiconductor
concerning its FDS881XNZ series
- take a look at MOSFETs survive larger voltage spikes
which says: "Low-on-resistance N-channel MOSFETs boost system efficiency and offer new levels of ESD prptection".
Take a look also at the news release from Acces I/O Products, Digital I/O boards are optically isolated,
as well as ORing power controllers improve power distribution from Texas Instruments (April 2006-),
and T-filters provide EMI protection from Syfer Technology.
