Description
The Delta BUB0705H-CS11 is a 5VDC 75x75x30mm Blower optimized for high-impedance thermal environments where space-constrained cooling is critical. Engineered with a DC brushless motor and advanced bearing architecture, this centrifugal fan minimizes thermal impedance by delivering concentrated airflow through a 90-degree discharge. The unit operates at a rated current of 0.50A, providing the necessary torque to maintain consistent RPM under back-pressure. Its structural rigidity and precision-balanced impeller ensure low-vibration operation, making it an ideal replacement fan for compact electronics requiring active heat dissipation and precise speed control via its 4-wire PWM interface.
