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

Pd =
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.
