9A0824G401 Обзор
A DC axial fan is a brushless motor-driven impeller that moves air parallel to the shaft; this category sits within the broader cooling solutions hierarchy: DC fan -> axial fan -> cooling fan -> thermal management -> electromechanical component. Because this part carries a tachometer output, it falls into the "intelligent fan" sub-class used in systems where the host must know whether the fan is actually spinning rather than just commanding it to start.
Key features include the 80 mm square frame, 25 mm thickness, 53.0 CFM airflow at 40 dB(A) noise, dual-ball bearing construction, and a rated MTBF consistent with the San Ace 80 line. The three-wire interface exposes VCC, GND, and a tachometer (FG/RD) signal so an FPGA, MCU, or supervisor can detect stall conditions and trigger system shutdown or throttling.
Typical applications include 1U/2U rack-mount servers, telecom base-station and switching equipment, industrial inverters and PLCs, medical imaging chassis, and any 24 V-brushless application where cooling telemetry is required. Designers select this fan when 24 V is the available rail and a tach signal must feed a supervisory circuit for thermal safety.
When designing with this part, route the tach signal away from switching power stages and place a small RC filter (typ. 1 kΩ + 1 nF) at the controller input. The datasheet operating range of 12 V to 26.4 V permits use on 12 V systems at reduced airflow, but the rated airflow and noise figures are specified only at 24 V.

Типичное применение
9A0824G401 подходит для 6 применениеs: 1U/2U Rack Server Cooling, Telecom Base Station Equipment, Industrial Inverter and PLC Cooling, Medical Imaging Chassis Thermal Management, Network Switch and Router Line Cards, Industrial Panel PC and HMI Cooling.
1U/2U Rack Server Cooling
The 9A0824G401 fits 1U/2U rack servers because its 80x80x25 mm low-profile frame and 53.0 CFM airflow match the typical airflow-density requirement of a single-CPU server at 24 VDC rail. Placed as exhaust or intake fan behind the CPU heatsink, the tachometer output lets the BMC or platform controller detect rotor stall and trigger thermal shutdown to protect the processor. Compared with a 12 V fan, the 24 V design reduces supply current by half, easing distribution losses across the backplane.
Рекомендуется
Telecom Base Station Equipment
The 9A0824G401 fits telecom base-station and switching equipment where 24 V or -48 V-rectified-24 V rails are standard and reliability is critical. Its dual-ball bearing tolerates higher ambient temperatures found in outdoor or sealed cabinets, and the tachometer wire feeds back to the supervisory ASIC for stall alarm. The 53.0 CFM airflow is well matched to cooling radio modules and baseband processors in a compact chassis.
Рекомендуется
Industrial Inverter and PLC Cooling
The 9A0824G401 is well suited to industrial inverter and PLC chassis because the 80x80x25 mm format is a standard cutout size in industrial enclosures, and the tachometer output supports the SIL/PL safety monitoring that detects fan failure. Operating from a 24 V industrial control rail, the fan draws low current and integrates directly with PLC fan-control outputs. Ball-bearing construction handles the higher ambient temperatures typical of factory-floor cabinets.
Рекомендуется
Medical Imaging Chassis Thermal Management
The 9A0824G401 fits medical imaging chassis such as ultrasound systems and portable X-ray controllers where 24 VDC is the standard internal rail and the dual-ball bearing's long service life supports the long product life of medical capital equipment. The 40 dB(A) noise rating keeps the acoustic profile low for clinical environments, and the tachometer wire can drive a service-due indicator. Its compact 25 mm depth accommodates slim imaging-cart form factors.
Рекомендуется
Network Switch and Router Line Cards
The 9A0824G401 is well matched to network switch and router line-card cooling because its 24 VDC rating aligns with the -48 V telecom bus after DC-DC conversion, and the 80x80x25 mm form factor is the de-facto line-card cooling standard. The tachometer output integrates with switch ASIC telemetry to flag thermal events, while 53.0 CFM airflow handles multi-port switch ASICs and PoE power supplies in a compact 1U line card.
Рекомендуется
Industrial Panel PC and HMI Cooling
The 9A0824G401 fits industrial panel PCs and HMI displays that operate continuously on factory floors and require reliable, long-life cooling. The dual-ball bearing handles 24/7 operation at elevated ambient temperatures, while the 3-wire tachometer output allows the HMI's embedded OS to display fan-health status to maintenance technicians. The 25 mm depth profile is suitable for the slim rear-panel cutouts of panel-mount HMI enclosures.

Заметки по проектированию
Estimated: At 24 VDC nominal and a typical 80 mm axial fan rated current of 0.10-0.15 A, the 9A0824G401 draws roughly 2.4 W to 3.6 W. Provide a 24 V rail capable of at least 0.20 A inrush headroom; use a 100 uF/35 V aluminum-polymer bulk capacitor near the fan connector to absorb the inrush spike when the fan spins up from a stalled rotor. Decouple the tachometer signal with a small RC filter (1 kΩ + 1 nF) to suppress brush-commutation noise picked up by long cable runs.
The 9A0824G401 itself does not require a heatsink, but it is intended to remove heat from a system. Verify that the chassis intake path provides at least 53.0 CFM of unrestricted airflow; obstructed intakes (filters, blank plates) will derate the effective cooling capacity. For a 1U server application, plan for one 9A0824G401 per ~150 W of dissipated power at typical system back-pressure. If the chassis uses a dust filter, account for 20-30% airflow derating over time as the filter loads.
Do not hot-swap a fan while the host system is fully loaded unless the system has N+1 cooling redundancy; pulling a fan in a single-fan 1U server can cause immediate thermal shutdown of the CPU. Also, do not block the rotor with a foreign object during burn-in; stalled-rotor current can be 2-3x nominal and may trip the supply's overcurrent protection. Finally, route the tachometer wire away from switching power-stage switching nodes - the tach signal is a low-amplitude open-collector pulse and is easily corrupted by nearby dV/dt.
