Chassis Mount

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
