Metal-Mite

Aluminum Housed

Axial Terminal Wirewound, 1% Tolerance

The 89 Series is a high-performance axial type

resistor. These molded-construction metal-housed

resistors are available in higher power ratings than

standard axial resistors and are better suited to with-

standing vibration, shock and harsh environmental

conditions.

The 89 Series Metal-Mite

resistors are aluminum

housed to maintain high stability during operation

and to permit secure mounting to chassis surfaces.

The metal housing also provides heat-sinking

capabilities.

89 series

F e at u r e s

• High Stability: ±0.5% ∆R

• High power to size ratio

• Metal housing allows chassis mounting and pro-

vides heat sink capability

Derating

Linearly from 100% @ +25°C to 0% @ +275°C.

Tolerance

±1% and ±5% (other tolerances available).

Power rating

Rating is based on chassis mounting area and temperature stability. Proper heat sink as follows: 5W and

10W units, 4” x 6” x 2” x .040” Aluminum chassis; 25W units, 5” x 7” x 2” x .040” Aluminum chassis;

50W units, 12” x 12” x .059” Aluminum panel.

Maximum ohmic values

See chart.

Overload

5 times rated wattage for 5 seconds.

Temperature coefficient

Under 1Ω: ±90 ppm/°C; 1 to 9.99Ω: ±50 ppm/°C; 10Ω and over: ±20 ppm/°C.

Dielectric withstanding voltage

5W and 10W rating,1000 VAC; 25 and 50W ratings, 2250 VAC.
