805NFR005E Datasheet, PDF (1/1 Pages) Ohmite Mfg. Co. – Metal-Mite® Aluminum Housed Axial Term. Wirewound, 1% Tolerance

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.
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 capabili-
ties.
FEATURES
• High Stability: ±0.5% ΔR.
• High power to size ratio.
• Metal housing allows chassis
mounting and provides heat sink
capability.
As of September 2006,
the 89 Series is no longer
offered as Mil. Spec.
SPECIFICATIONS
Material
Housing: Metal, anodized alumi-
num.
Internal Coating: Silicone.
Core: Ceramic.
Terminals: Solder-coated axial.
Derating: Linearly from
100% @ +25°C to 0% @
+275°C.
Electrical
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 chas-
sis; 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.

handling charge per item
Shaded values involve very fine resistance wire and
should not be used in critical applications without
burn-in and/or thermal cycling.
