Wirewound Resistors, Commercial Power,
Silicone Coated, Axial Lead
FEATURES
High temperature coating (> 350 °C)
All welded construction
Available with “vitreous like appearance
coating as ALVR
Available in non-inductive styles with Ayrton-
Perry winding for lowest reactive components,
special “NI”
For non-inductive models, divide maximum
resistance values by two
Material categorization: for definitions of
compliance please see www.vishay.com/doc?99912
Notes
(1) Vishay Huntington ALSR / ALVR models have two power ratings depending on operation temperature and stability requirements. Models
not available for characteristic V are: ALSR01, ALVR01, ALSR03, and ALVR03
