Features
The LRD product series are designed to reduce
the device’s resistance at the same hold cur-
rent rating. The smaller thermal mass of these
devices also provide benefit of faster trip time and
increase the battery safety level. The LRD devices
are ideally suited for battery packs used for
portble computer and camcorder applications.
