High Power SMD Wirewound Resistors | OhmiteFor a number of years Ohmite and other resistor companies have worked to develop an SMD wirewound resistor which could meet the 5W power rating or above.  Ohmite's solution was to incorporate "fins" in the resistor body similar to a heatsink to achieve the higher power rating.  This creates the additional surface area to the resistor body without having to grow the envelope of the part to an excessive size.  Resistance range for the 5 watt part is 0.1 ohms to 50K ohms and 0.1 ohms to 100K ohms for the 7W part.  

Features & Benefits:

  • Finned design facilitates cooling
  • High Power Density
  • Wide Resistance Range
  • Tight Tolerance
  • Low TCR
