High stability and low temperature coefficient are the main features of the precision wirewound resistors type RMB RMBS
models just as maintenance parts. Their performances can be compared with those of the best film resistors but they have in
addition a greater power rating. RMBS styles meet the more severe requirements of NF C 83-210 (all RMBS styles are approved)
and characteristic U of MIL-R-26 E (approximate size of RW 70 and 79 resistors) specifications. The two models RMB and
RMBS have a similar construction. RMBS are submitted, in addition to a process which further increases the stability. On
request, non-inductive resistors are available under the reference RMB NI.
