Surface-mount
PolySwitch Surface-mount
Resettable Devices
More than ten years ago,
Raychem Circuit Protection intro-
duced the SMD product family,
and polymeric PTC devices
quickly became the computer
industry standard for keyboard,
mouse, and disk drive protection.
In 1995, Raychem Circuit
Protection advanced the technol-
ogy, reducing the size and cost of
surface-mount resettable devices
with the introduction of its
miniSMD product series. The
recent additions to the surface-
mount family include the
nanoSMD series, which reduces
the size to a 3216mm (1206mils)
foot print, one-third the size of the
popular miniSMD series.
