Note:
I
hold
= Hold current: maximum current device will pass without tripping in 20
I
trip
=
Trip current: minimum current at which the device will trip in 20
V
max
= 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 (V
max
)
P
d
= Power dissipated from device when in the tripped state at 20
R
min
= Minimum resistance of device in initial (un-soldered) state.
R
1max
= Maximum resistance of device at 20
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
Specifications are subject to change without notice.

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.
