Surface Mount Resettable PTCs

The SMD2018 Series PTC provides surface mount

over-current protection for applications where space is at a

premium and reset table protection is desired.



RoHS compliant, Lead-Free and Halogen-Free

Fast time-to-trip



Compact design saves board space

Agency recognition: UL

Low-profile

Almost anywhere there is a low voltage power supply, up to

30V and a load to be protected, including:



Computer mother board, Modem. USB hub

PDAs & Charger, Analog & digital line card

Digital cameras, Disk drivers, CD-ROMs

Power ports



General electronics

I _hold= Hold current: maximum current device will pass without tripping in 25°C still air.

I _trip= Trip current: minimum current at which the device will trip in 25°C still air.

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_dtyp.= Power dissipated from device when in the tripped state at 25°C still air.

R _min= Minimum resistance of device in initial (un-soldered) state.

)

R _max= Maximum resistance of device in initial (un-soldered) state.

R _1max= Maximum resistance of device at 25°C measured one hour after tripping.

Caution: Operation beyond the speciﬁed rating may result in damage and possible arcing and flame.
