Description
Sunon EE40101S1-1000U-999 (also known as EE40101S11000U999) is a compact, low-profile DC brushless tubeaxial cooling fan engineered in a standardized 40 x 40 x 10 mm (1.57 x 1.57 x 0.39 in) frame. Powered by a 2-phase, 4-pole brushless motor running on 12 VDC, it delivers an airflow of 8.2 CFM (13.93 m³/h) and static pressure of 0.19 in H₂O (47.3 Pa) at 7,300 RPM while consuming merely 0.99 W (82 mA). Constructed with flame-retardant UL 94V-0 thermoplastic PBT housing and impeller, the unit incorporates a precision lubricated sleeve bearing system, automatic locked-rotor restart, and polarity protection. Electrical connection is routed via 300 mm (11.81 in) 26 AWG lead wires, ensuring seamless integration into space-constrained electronic assemblies.
Key Features
- High-Speed Tubeaxial Aerodynamics: Delivers 8.2 CFM airflow and 0.19 in H₂O pressure at 7,300 RPM for dense assemblies.
- Ultra-Low Power Motor: Consumes only 0.99 W rated power at 12 VDC with wide 4.5–13.8 VDC operational range.
- PBT Flame-Retardant Build: Frame and impeller molded from rugged UL 94V-0 rated thermoplastic for industrial durability.
- Integrated Circuit Protection: Features locked-rotor automatic restart recovery within 10 seconds and reverse polarity protection.
- Compact 10mm Profile: Ultra-slim 40x40x10 mm footprint enables targeted cooling in height-critical chassis and enclosed modules.
