Description
EFB0512HA Delta 50x50x10mm Ball 12VDC 11.40CFM(0.323m3/min) 0.167inchH2O(4.24mmH2O) 30.0dB(A) 1.20W 5500RPM 2wireleads fan
Delta EFB0512HA is a DC brushless axial flow fan with a nominal voltage of 12VDC (operating voltage 7.0-13.8VDC), maximum input current of 0.15A, power of 1.80W, and rotational speed of 5500RPM. It delivers a maximum air flow of 0.323m³/min (minimum 0.291m³/min) and maximum static pressure of 4.24mmH₂O (minimum 3.43mmH₂O), with an average acoustic noise of 30.0dB(A) (maximum 35.0dB(A)). Measuring 50.0×40.0×10.0mm and weighing 25g, the frame and impeller are made of UL 94V-0 flame-retardant plastic, equipped with double ball bearings and rotating clockwise when viewed from the nameplate side. It uses UL 2468-F AWG#28 leads (red for positive, black for negative), operates at -10°C to 70°C, stores at -40°C to 75°C, and has a working humidity of 5%-90%RH. With locked rotor protection (preventing fire within 96 hours of lock-up) and reverse polarity protection, it has a lifespan of 70,000 hours at 40°C and 15%-65%RH, suitable for low-power cooling in small electronic devices.
