POLYSWITCH RESETTABLE
DEVICES
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, Littelfuse PolySwitch team 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.

Solder Reflow
Recommended reflow methods:
- IR
- Hot air
- Nitrogen
Recommended maximum paste thickness: 0.25mm (0.010in)
Devices can be cleaned using standard methods and aqueous solvents.
Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is
placed underneath each device’s termination. As such, we request that customers comply with our recommended solder pad layouts.
Customer should validate that the solder paste amount and reflow recommendations meet its application.
We request that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch
devices. It is possible that raised features could negatively impact solderability performance of our devices.
Rework
femtoSMD, picoSMD, nanoSMD, microSMD, miniSMD and SMDC series: standard industry practices.
(Please also avoid direct contact to the device.)
SMD series: Rework should be confined to removal of the installed product and replacement with a fresh device.

Warning :
Users should independently evaluate the suitability of and test each product selected for their own application.
Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used
when repeated fault conditions or prolonged trip events are anticipated.
Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical
procedures for electronic components.
PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example
in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion.
Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.
