The 89 Series is a high-per-
formance axial type resistor.
These molded-construction
metal-housed resistors are
available in higher power rat-
ings than standard axial resis-
tors and are better suited to
withstanding vibration, shock
and harsh environmental con-
ditions.
resistors are aluminum housed
to maintain high stability during
operation and to permit secure
mounting to chassis surfaces.

ties.
