Ultra Precision Wire-Wound Resistors
Type UPW Series
Key Features
I
Custom weld tabs and
copper weld leads ensure a
good mechanical and
electrical connection
between the element and
the lead wires.
Protection is given to the
windings by means of a
layer of silicone RTV
rubber. This allows
movement of the windings
during temperature
cycling due to loads and
to varying ambient
temperatures. Outer
protection is given by
means of a hot transfer
moulded epoxy compound
which ensures an airtight
I
coating with no trapped air
Superior quality wire-
wound resistors with very
low selection tolerances
and temperature
coefficients down to 1 ppm.
3 case sizes are available.
T/C, ratio and pair
matching is available
The resistive element is wire wound onto a moulded high temperature plastic bobbin with
a central former. The direction of winding is reversed part way through the winding,
giving very low values of inductance. These Neohm resistors use bobbin assemblies with
flattened lead ends, providing high resistance to pull, vibration and torsional forces
during handling, assembly and life.
