• Termination = Sn/Ag/Cu or pure matte tin according to the
ohmic value
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.
