at normal operating hold
current)
• RoHS compliant, Lead
Free and Halogen Free
• Fast response to fault
currents
• Compact design saves
board space
• Thin-profile <0.75mm
• Compatible with high
temperature solders
Applications
• USB peripherals
• Disk drives
• CD-ROMs
• PDAs / digital cameras
• Plug and play protection
for motherboards and
peripherals
• Game console port
protection

Note:
*1812L350 Typical Time-to-Trip is 50A at 0.013-0.020 seconds and meets the 8A at 5 seconds maximum Time-to-Trip requirement.
**1812L350 R1min=0.015ohm (resistance range 0.015-0.025ohm).
I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
I trip = Trip current: minimum current at which the device will trip in 20°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 (Vmax)
P d = Power dissipated from device when in the tripped state at 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow
soldering of 260°C for 20 sec.
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
