The LR4 devices’ smaller thermal mass
means reduced reaction time to over-
current events. The LR4 devices are
suited for battery packs intended for
computer and camcorder applications.
The SRP products help provide reliable,
non-cycling protection for rechargeable
batteries. Weldable nickel leads and a
narrow, low-profile design make these
devices easy to install directly onto
battery cells.
