Resistance Wire
Mills selects the optimal type and size of
resistance wire alloy for winding its resistors
based upon the physical size of the resistor and
the resistance and temperature coefficient
required. These typically non-magnetic alloys
possess properties that enhance the utility of
each resistor manufactured, including high
electrical resistivity, low temperature coefficient
of resistance ( 10 ppm/ºC) over a wide tempera-
ture range (-65ºC to 125ºC), low thermal EMF
vs. copper, and high tensile strength. The high
resistivity of these alloys allows Mills to place
very high resistance values in very small
packages. In addition, Mills uses other alloys to
achieve temperature coefficients of up to 6,000
ppm/ºC.
Termination
All ultra-precision resistors produced by Mills are
welded in the sandwich or layered style to
guarantee accuracy and stability. All welding is
performed under high-power binocular micro-
scopes. Welding equipment, electrode pres-
sures and heat cycles are monitored regularly.
Terminal materials are selected for maximum
weldability and low thermal EMF.
Lead Material
On our standard resistors, the solder coated,
oxygen free copper lead is molded into the
winding bobbin to assure structural integrity.
Other lead materials are possible; Nickel, Brass,
and Dumet are some of the more popular.
Bobbins
Bobbins are made from molded high tempera-
ture epoxy. The thermal expansion properties of
this product is similar to the wire used in the
resistor and designed to minimize any stress on
the resistor due to environmental changes.

Quality Control
Mills Resistor meets all applicable quality assur-
ance standards. Our quality control manual is
available upon request.
Encapsulation
After the resistor has been wound, terminated,
and aged, a special coating is applied to the
windings to further protect the windings during
the encapsulation process. An epoxy resin
specially selected because its linear expansion
capabilities match that of the wire is used to
encapsulate the resistor element.
Wattage Ratings
The wattage ratings listed on the following pages
for ultra-precision wirewound resistors are
maximum wattage ratings. They are based upon
an ambient temperature of 125ºC. Ultra-preci-
sion wirewound resistors should not be used at a
combination of full wattage and maximum ambi-
ent temperature where reliability is an important
factor. When high reliability is required, a multi-
plication factor of 0.6 should be applied to the
wattage listed. Also as tolerances get tighter, the
resistor can only operate at a fraction of its rated
power (see derating chart).

    ... In calling out the ohmic value, all digits are significant; we use a letter designator as the decimal point for the multiplier. The standard configuration for the MR100, MR300, MR93, and MR500 series resistors is axial leads with diameters as indicated in the above tables. Additional configurations are possible; please see the inside back cover for more options. ...

Limitations do exist in measuring two-leaded resistors, so there are minimum practical tolerance limits depending upon the resistance required. The following tables shows these ...
