Molded Precision Wirewound Resistors
Axial Leads
FEATURES
• 0.75 W to 3 W at 25 °C
• NF C 83-210
• CECC 40201-005
• Low temperature coefficient ≤ 50 ppm/°C
• Low ohmic values 15 mΩ available
• Excellent behavior against humidity
• Electrical insulation
• Mechanical strength
• Accurate sizes
• Termination = Sn/Ag/Cu or pure matte tin according to the
ohmic value
• Compliant to RoHS directive 2002/95/EC
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.

STABILITY AND POWER RATING
Stability changes slightly according to power rating and ambient temperature. This fact is specially important for users needing
a life drift lower than the initial resistance tolerance. Typical drifts, after 2000 h life test made under the 90’/30’ conditions and at
a 25 °C ambient temperature are:
