The SMD0805Series 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 16V and a load to be protected,including:

◆Computer mother board,B hub ◆PDAs &Charger,Analog &digital line card ◆Digital cameras,Disk drivers,CD-ROMs ◆USB peripherals ◆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.
