FEATURES
• Molded construction for total environmental
protection
• Complete welded construction
• Available in non-inductive styles (NI special)
with Ayrton-Perry winding for lowest reactive
components
• Mounts on chassis to utilize heat-sink effect
• Excellent stability in operation (< 1 % change in
resistance)
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
Note
• The NI is for two digit “special” number to indicate a non-inductive part.
