Devices for Battery Pack Applications
VTP
The conductive polymer composite in
the VTP battery overcurrent protection
devices provides increased safety with
extended battery run time. These devices
reach a high-resistance state at lower
temperatures in NiMH and rechargeable
lithium temperature-sensitive chemistries.

LR4
LR4 battery protective devices’ lowresistance material is combined with our
proven strap product design to increase
the operating range of these devices. The
smaller thermal mass of the devices also
means reduced reaction time to overcurrent events. The LR4 devices are ideally
suited for battery packs intended for
computer and camcorder applications.
