DESCRIPTION:
The
PDI-E834
is a three drive line dual
emitter oximeter component. The 660 and 905 nm GaAlAs
emitters are high power LPE grown. The metalized ceramic
has clear epoxy encapsulation with top side solder pads.
These components are ideal for O.E.M. and repair replace-
ments of oximeter probe assemblies.
