Wirewound Resistors, Industrial Power,

Aluminum Housed, Chassis Mount

FEATURES

•

Molded construction for total environmental

protection

• Complete welded construction

•

Meets applicable requirements of MIL-PRF-18546

• Available in non-inductive styles (type NH) with

Ayrton-Perry winding for lowest reactive

components

• Mounts on chassis to utilize heat-sink effect

• Excellent stability in operation (< 1 % change in

resistance)

• MIL-PRF-18546 qualified, type RE resistors can

be found at: www.vishay.com/doc?30282

• Material categorization: For definitions of

compliance please see www.vishay.com/doc?99912

Note

* Lead (Pb)-containing terminations are not RoHS-compliant. Exemptions may apply.
