SUNON HA40101V4-000U-999 addresses assembly cooling in data centers and communication assembly with a DC axial fan architecture suited to repeatable installation and service identification.
The straight-through ventilation flow geometry simplifies integration into panels, cabinets and assembly zones that need broad air exchange.
The listed 12 V supply and 0.38 W input give electrical designers a defined basis for power and interface planning.
Assembly designers gain a traceable cooling specification that can be reviewed by engineering, purchasing and maintenance teams. Keep the model reference unchanged in replacement documentation. Check environmental limits in the original product data. Confirm the exact operating point before production release.
For equipment in servers and data-communication hardware, SUNON HA40101V4-000U-999 acts as a thermal control component that cools computing and network assemblies. Installation resistance can shift delivered airflow away from free-air catalogue values if it is not checked.
The application of HA40101V4-000U-999 covers power supplies, inverters and control cabinets; here, the DC axial fan cools power modules and controls. A defined air route supports repeatable thermal behavior across production units and service replacements.
The SUNON DC axial fan HA40101V4-000U-999 addresses thermal demand in industrial automation installation by helping to ventilates drives and production electronics. Purchasing teams gain a traceable model reference for controlled sourcing and compatible maintenance replacement.
HA40101V4-000U-999 aids medical and laboratory instruments by using its DC axial fan format to cools enclosed instrument electronics. The application values controlled ventilation because internal space and acoustic limits constrain thermal control choices.
Confirm the target equipment, operating point, ambient conditions, installation space, electrical supply, controls, protection, quantity, and required delivery date.
The upload row lists RoHS compliance, but no additional exact-model certification is confirmed in the supplied feature record.
No exact IP protection level is stated for this item in the supplied sources. Confirm it before use in dusty, wet, or harsh locations.
The upload row lists 15.7 dB. Confirm the measurement condition and compare noise at the intended operating point.
The matched source highlights axial airflow intended for low-to-moderate system resistance. Compare that point together with the listed electrical and dimensional data.
The supplied row lists 9.2 m³/h airflow, 22.4 Pa pressure, 0.38 W input, 5000 rpm, 15.7 dB. Compare these values with the real system operating point, not only the free-air rating.

Within telecom cabinets, base stations, and network equipment, SUNON HA40101V4-000U-999 serves as a 40 × 40 × 10 mm DC axial fan operating at 12 VDC. A listed noise value of 15.7 dB is the model's key differentiator. Use the documented application data when planning airflow-path design. Obtain the applicable curve before final duty-point approval.
