描述

CBM-5020V-148 is a 12 VDC brushless DC blower fan designed for compact cooling applications with a 50 x 50 x 20 mm frame size. It features an 8-pole DC brushless motor with omniCOOL bearing system and delivers a rated speed of 4800 RPM (±10%) at 25°C after 10 minutes of operation. The fan produces 5.2 CFM of airflow at 0 inch H2O static pressure and 0.56 inch H2O maximum static pressure at 0 CFM, with a maximum noise level of 33.0 dBA measured at 1 m. It operates across an input voltage range of 6–13.8 VDC with a maximum input current of 104 mA and maximum input power of 1.3 W, and includes auto restart protection that automatically restarts the motor when a locked rotor condition is released. The fan is suitable for thermal management in compact electronic equipment, industrial controls, and consumer appliances requiring reliable, quiet cooling performance.
