Characteristic
Damper torque (23°C ambient temperature) changes with speed. Typically, torque increases with increasing rpm, as shown in the figure above
Temperature - torque characteristic (20r/min)
The torque of the damper (speed: 20r/min) changes with changes in ambient temperature. Typically, torque increases at lower temperatures and decreases at higher temperatures, as shown in the graph above
