LBA127L
DS-LBA127L-R4
LBA127L is 250V, 200mA, 10
independent 1-Form-A
and 1-Form-B relays. It features a superior combination of
low on-resistance and enhanced peak load current han-
dling capabilities. Current limiting version is available ("L"
suffix, see specification for variations in performance).

Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for an extended period may degrade the device and effect
its reliability.
