  • Lead Material: Tinned Copper.
  • Without a Heat Sink, when in Free Air at 25°C, the RMG20 is Rated for 2.25W.
  • The Case Temperature is to be used for the Definition of the Applied Power Limit.
  • The Case Temperature Measurement Must be Made with a Thermocouple Contacting the Center of the Component Mounted on the Designed Heat Sink.
  • Thermal Grease Should be Applied Properly.
