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
