  • Lead Material: Tinned Copper
  • Without a Heat Sink
  • When in Free Air at 25°C, the TP20 is Rated for 3W
  • 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
