Clare's Ultra-Mini Dyad
TM
is well suited for small, signal
switching applications. The small size lends itself to surface
mountable applications; working well on higher density
PC boards. The Ultra-Mini Dyad
TM
has sputtered ruthenium
contacts and an extraordinary seal strength achieved by
a patented laser sealing of the leads. In low level or dry
switching environments, switches typically exceed 1 billion
operations.

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 extended period may degrade the device and effect
its reliability.
