RNF/RNMF Series
General Purpose Metal Film Resistor
Stackpole Electronics, Inc.
Resistive Product Solutions
Features:
• Precision metal film
• Superior electrical, TCR performances
• Flame-retardant coatings are standard
• Panasert available (selected sizes: contact factory)
• RNMF (mini) an ideal choice where size constraints apply
• RNS (ultra-mini) for tight size constraints
• RNF 5% replaces MP series
• RoHS compliant / lead-free
• Lower or higher resistance values may be possible (contact factory)
