Cymbal Thermal Data
• Free air convection thermal resistance (θ): Approximately 3.6 to 4 °C/W.
• Thermal time constant: Approximately 40 minutes/ 2400 seconds (thermal time constant
means that the Cymbal will reach 2/3 of its final temperature after 4 minutes).
• Self heat dissipation capability (no external heatsink): 12 W for 40 °C/W temperature rise.
• Shut‐off temperature: 86 °C to 88 °C (measured on the heatsink).
• The thermal resistance when connecting to an external heat sink:
The surface of the external heatsink is 50 μm: 0.18 °C/W.
Thermal conductive compound. By proper Smearing of the surface a significant
improvement of the thermal resistance is achieved: 0.13 °C/W
