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:

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
