※ Thermal resistance test condition• Ambient air cooling.
• Heat-sink fins are set perpendicular to the ground with temperature at 60°C.
• Powder coated aluminium diecast.
• Heat source is applied on the opposite side (inner side) of the fins.

Temperature measurement test
Raspberry Pi board is placed into the RPH-4B-H model and a commercially available Raspberry Pi plastic case.
Temperature is measured after 6 hours of continuous operation.
*Results will vary depending on usage period and environment. Listed values are in-house test reference values only.
