4.14. Heat Dissipation
The best way to dissipate heat from the Gold Hornet is to mount it so that its heat sink faces
up. For best results leave approximately 10 mm of space between the Gold Hornet's heat sink
and any other assembly.
4.14.1. Thermal Data
• Heat dissipation capability (θ): Approximately 10 °C/W
• Thermal time constant: Approximately 240 seconds (thermal time constant means that the
Gold Hornet will reach 2/3 of its final temperature after 4 minutes)
• Shut-off temperature: 86 °C to 88 °C (measured on the heat sink)
4.14.2. Heat Dissipation Data
