SMD2920 Surface Mount PTC Devices R.O.C. Patent#415624
l The SMD2920 Series, a polymer-based Positive Temperature Coefficient (PTC) device to
protect electrical circuits against overcurrent conditions with resettable feature, is fully
compatible with current industrial standards.
l The new designed SMD2920 Series provides surface mount overcurrent protection with
superior performance.
l Application: The SMD2920 Series is ideal for computers and peripherals and can be applied to
almost anywhere there is a low voltage power supply and a load to be protected.
l The solder plated termination is designed to meet or exceed solderability specifications and
provide excellent solder joint inspectability.
l Agency Approval: UL File # E201431.
CSA File # CA115375-1

Note:I hold = Hold current: maximum current device will pass without tripping in 20℃ still air.
I trip = Trip current: minimum current at which the device will trip in 20℃ still air.
Vmax = Maximum voltage device can withstand without damage at rated current (I max
)
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax
Pd = Power dissipated from device when in the tripped state at 20℃ still air.
R min= Minimum resistance of device in initial (un-soldered) state.
)
R 1max= Maximum resistance of device at 20℃measured one hour after tripping or reflow soldering of 260℃ for 20 sec.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
