Token Electronics extended lead wire aluminum housed
power AHL series provides design engineers a flexible
connection in distance between connections
AHL is a high-performance axial-terminal type resistor
with flexible connections. These molded-construction
aluminum-chassis resistors are available in higher power
ratings than standard axial-terminal resistors and are
better suited to withstanding vibration, shock and harsh
environmental conditions.
AHL 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, allowing the units to exceed the power ratings.
The AHL Series is RoHS compliant and lead free. For non-standard technical requirements and custom special
applications, please contact us for details with your specific needs.
Non-Inductive :
Ayrton Perry type non-inductive winding is available. When required add “N” to the part number.
Features :
● High stability, strong construction.
● Standard winding & non-inductive winding types.
● High power rating, small size and ultra precision.
● Aluminum housing allows chassis mounting and provides heatsink capability.
General Specification :
● Resistance Tolerance: ±10%, ±5%.
● Operating Temperature Range: -55°C to +275°C.
● Wattage Range: 4 styles to choose ranging from 25 to 150 watts.
● Dielectric Strength: AHL-25 1000V, AHL-50 1500V, AHL-150 2500V.
