ELECTRICAL SPECIFICATIONS

Minimum Values:

0.1 ohm for

1% and

0.5%.

10 ohm for

0.1% and tighter.

Resistance Tolerance:

0.005%,

0.01%,

0.02%,

0.05%,

0.1%,

0.5%, and

1%, depending on style

and value.

Temperature Coefficient:

10 ppm/°C standard for 10

ohm and above. Higher T. C.’s on low ohmic values. T. C.

match to

1 ppm/°C. High T. C.’s up

to + 6000 ppm/°C are available.

Standard temperature range:

– 10°C to + 80°C.

Working temperature range:

– 60°C to + 145°C.

CONSTRUCTION

All Welded Construction:

The combination of all welded

construction and compatible materials provide the most

reliable means of interconnects possible.

Butt Weld of Tab to Lead:

A tab material of

800 ohm alloy (the same as the resistance wire)

is butt welded to the lead and molded deep into

the resistor bobbin. This design parameter assures the least

possible D. C. transients due to thermal EMF.

Bobbin Design:

The ratio of the height of the Pi wall to the

width of the Pi and to the diameter of the bobbin mandrel

are critical to the basic stability of a wirewound resistor.

These parameters are optimized for each wire size, wattage

size and range of resistor values.

Encapsulation Material:

Both the bobbin and the final

encapsulation material are thermosetting alkyd polyester.

The resulting resistor is virtually a homogeneous mass with

an identical coefficient of expansion which is unaffected by

the most violent of temperature cycling. All types are

unaffected by application of solvents.

Lead Materials:

The standard lead material is hot solder

dipped copper (C5N). Other available materials are bare

nickel (N1N) and gold plated nickel (N2N).
