Description
The Delta AFB03512MA-CF00 (also known as AFB03512MACF00) is a compact, high-reliability brushless DC axial cooling fan measuring 35 × 35 × 10 mm (1.38 × 1.38 × 0.39 in) designed for micro-thermal management in tight enclosures. Operating on a nominal 12 VDC supply across a 4.5 to 13.2 VDC range, this unit delivers an airflow of 4.27 CFM (7.26 m³/h) and static pressure of 0.076 in H₂O (19.0 Pa) at 5800 RPM while consuming merely 0.60 W. Engineered with a precision dual-ball bearing assembly and UL 94V-0 flame-retardant plastic housing and impeller, it ensures sustained L10 reliability of 30,000 hours at 40°C. Electrical integration is streamlined via three 150 mm UL 1061 AWG #26 lead wires providing power, ground, and an open-collector frequency generator (FG) tachometer speed-monitoring signal.
Key Features
- Dual Ball Bearing Architecture: Sustains an L10 operating life of 30,000 hours at 40°C and 65% relative humidity.
- Frequency Generator Tachometer Output: Features a dedicated open-collector third-wire FG output delivering 2 pulses per revolution for system diagnostics.
- Compact Low-Profile Micro Frame: Ultra-slim 35x35x10mm envelope optimizes airflow in space-constrained embedded enclosures and compact 1U server blade configurations.
- Comprehensive Circuit Safety Protection: Integrates reverse polarity protection and 96-hour locked-rotor impedance protection to prevent winding overheating under stall conditions.
- Flame-Retardant Thermoplastic Build: Constructed with UL 94V-0 rated housing and impeller materials, complying with strict industrial flammability requirements.
