- 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.
