MELF Resistor Carbon Film - RDM series

MELF Resistor Carbon Film - RDM series

melf resistor

Features

  • Coating color : Yellow.
  • Marking : Color code (3 color band).
  • Free direction for mounting due to cylindrical design.
  • High solderability due to specially plated electrodes.
  • Electrodes strength is higher than flat chip resistors.
  • Lower current noise than thick film flat chip resistors.
  • Suitable for reflow, flow and iron soldering.
