825F25KE 数据手册

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.

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.
