Surface-Mount Devices
PolySwitch surface-mount devices are an
effective circuit protection method for computer,
consumer, multimedia, portable and automotive
electronics applications.
In an affort to reduce the size and cost of surface-mount
devices, TE Circuit Protection introduced the miniSMD
product series in 1995. Subsequently, we developed the
microSMD, nanoSMD, picoSMD and femtoSMD family of
products. The femtoSMD series reduced the device size
to a 1608mm (0603 mils) footprint, which is one-twelfth
the size of the popular miniSMD series.
Recent additions to the PolySwitch surface-mount series
include 1.1A picoSMD 1210mm (0805 mils) and 0.35A
femtoSMD 1608mm (0603 mils) devices.
