RN / RNM Series — General Purpose Metal Film Resistors
Features
• Precision metal film
• Superior electrical, TCR performances
• Flame-retardant coatings are standard
• Panasert available (selected sizes; contact factory)
• RNM (mini) an ideal choice where size constraints apply
• RN 5% replaces MP series
• RoHS compliant / lead-free available (RNF/RNMF)
• Lower or higher resistance values may be possible; contact
