Description
The Delta FFB1212EH-F00 (also known as FFB1212EHF00) is a high-performance 120 × 120 × 25.4 mm (4.72 × 4.72 × 1.00 in) DC brushless tubeaxial cooling fan engineered for high-density thermal management. Powered by an efficient 2-phase, 4-pole motor running on 12 VDC, it delivers up to 150.33 CFM (255.4 m³/h) of airflow and 0.489 in H₂O (121.9 Pa) static pressure at 4000 RPM. Built with a flame-retardant UL 94V-0 plastic housing and precision dual ball bearings, it ensures an L10 service life of 70,000 hours at 40°C. Standard electrical features include locked-rotor impedance shutdown, reverse polarity tolerance, a 10-second soft-start sequence, and a dedicated third-wire open-collector frequency generator (FG) tachometer speed sensor.
Key Features
- High-Flow Aerodynamic Design: Delivers up to 150.33 CFM of high static pressure airflow to overcome dense system impedance.
- Dual Ball Bearing System: Engineered for continuous duty cycle operation, offering an extended 70,000-hour service life at 40°C.
- Open-Collector Tachometer Output: Provides real-time frequency generator (FG) speed monitoring signals for thermal management closed-loop controllers.
- Soft-Start & Motor Protection: Integrates a 10-second soft-start routine along with locked-rotor current shutdown and reverse polarity safeguards.
- UL 94V-0 Rated Materials: Molded from flame-retardant thermoplastic for reinforced mechanical rigidity and strict fire safety compliance.
