PolySwitch Resettable Devices
Surface-mount Devices
PolySwitch surface-mount devices are the preferred
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, we 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, one twelfth the size of
the popular miniSMD series.
Recent additions to the PolySwitch surface-mount series
include 0.5A picoSMD 1210mm (0805 mils) and 0.35A
femtoSMD 1608mm (0603 mils) devices.
Benefits
• Smaller size saves board space and cost
• Many product choices give engineers more design
flexibility
• Compatible with high-volume electronics assembly
• Assists in meeting regulatory requirements
• Higher voltage ratings allow use in new applications
Features
• RoHS compliant
• Halogen free
(refers to: Br 900ppm, Cl 900ppm, Br+Cl 1500ppm)
• Broadest range of resettable devices available in the
industry
• Current ratings from 0.05 to 3A
• Voltage ratings from 6V computer and electronic
applications to 60V telecom applications
• Agency recognition: UL, CSA, TÜV
• Small footprint
• Fast time-to-trip
• Low resistance
Applications
• Computer
• Portable electronics
• Multimedia
• Game machines
• Telephony and broadband
• Mobile phones
• Automotive
• Industrial controls
• Battery
