*All resistors have an operating temperature range of -55°C to +275°C. Derating is required for reduced chassis mounting area
and for high ambient temperatures.
**To order non-inductive styles add suffix N (e.g.:ALN-5). (Divide Max. Res. Values by styles available with extended resistance
and tolerance ranges; contact factory.
Power Rating:
5 to 50 watts depending upon style. 275°C maximum hotspot at 25°C ambient. Conforms to MIL-R-18546.
1% maximum ∆R in 1000 hour load life. Proper heat sinks are as follows:
4 x 5 x 2 x 0.040 aluminum chassis - AL-5 and AL-10
5 x 7 x 2 x 0.040 aluminum chassis - AL-25 and AL-50
Construction:
Windings are "controlled stress" wound on ground ceramic cores. Terminations are of welded construction.
Terminals are electronically welded to the end caps for maximum strength and electrical continuity. A high
temp. silicone encapsulation is used to mold the wound assembly within the anodized
Standard Temperature Coefficient of Resistance:
<1 ohm = ±90 ppm
≥1 ohm to <10 ohms = ±50 ppm
≥10 ohm = ±20 ppm

Power Derating Curve
Ordering Data
Sample Part No.
AL resistors are rated to operate with a 275°C maximum hotspot under full rated power
at 25°C ambient. They must be derated for higher ambient temperature per "Wattage
vs. Ambient Temperature Derating Curve."
