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
*
This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details.
Note
• RH005 and NH005 printed with 5 W power rating. RH010 and NH010 printed with 10 W power rating. New construction allows these
resistors to be rated at higher wattage but will only be printed with the higher wattage upon customer request
