  • lead material: tinned copper.
  • maximum torque: 0.9 nm.
  • without a heat sink, when in free air at 25°c, the rmg35 is rated for 2.50w.
  • 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.
