Features
The new VLD product series feature a slim, low
profile and low resistance design. These devices
are ideal to install directly onto the latest genera-
tion batteries including cylindrical and prismatic
cells. The VLD product offers protection against
both overcurrent and overtemperature fault
conditions.

Hold current: maximum current device will pass without tripping in 25 °C still air.
Trip current: minimum current at which the device will trip in 25 °C still air.
Maximum voltage device can withstand without damage at rated current (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 25 °C still air.
R _min= Minimum resistance of device in initial (un-soldered) state.
R = _1max Maximum resistance of device at 25 °C measured one hour after tripping for 20 s.
Caution:Operation beyond the specified rating may result in damage and possible arcing and flame.
