Dissipation
3.10.1 Butterfly
The best way to dissipate heat from the Butterfly is to mount it so that its heatsink faces up.
For best results leave approximately 10 mm of space between the Butterfly's heatsink and any
other assembly.

3.10.1.1 Thermal Data
• Heat dissipation capability (θ): Approximately 10 °C/W.
• Thermal time constant: Approximately 240 seconds (thermal time constant means
that the Butterfly will reach 2/3 of its final temperature after 4 minutes).
• Shut-off temperature: 86 °C – 88 °C (measured on the heatsink)
