Frequently Asked Questions

What is SUNON HA40101V4-000U-C99?
HA40101V4-000U-C99 is a SUNON MagLev HA-series brushless DC axial cooling fan with a 40 x 40 x 10 mm frame, a 12 VDC rating and a three-wire speed-monitoring interface.

What is the rated voltage of HA40101V4-000U-C99?
DigiKey specifies 12 VDC with an operating voltage range of 4.5-13.8 VDC. The fan should be powered from a suitable regulated DC supply.

What are the dimensions of HA40101V4-000U-C99?
The dimensions are 40 x 40 x 10 mm. The related SUNON HA40101V4 series drawing shows a 32 mm mounting-hole center spacing, which should be checked against the actual C99 fan assembly.

What is the rated current?
The exact-model DigiKey specification lists 0.031 A, or 31 mA. Confirm the electrical information on the supplied fan if a precise current limit is required.

What is the power consumption?
DigiKey lists 0.43 W for HA40101V4-000U-C99. However, its listed 12 VDC and 0.031 A values multiply to approximately 0.372 W. The related SUNON HA40101V4-1000U-A99 catalog model is rated at 0.38 W. These differences should be resolved against the applicable fan label or exact-model specification rather than treated as identical.

What is the rated fan speed?
The published rated speed is 5000 RPM according to the exact-model DigiKey product specifications.

What airflow does HA40101V4-000U-C99 provide?
The documented airflow rating is 5.4 CFM, approximately 9.18 m³/h, under the specified test conditions.

What is the maximum static pressure?
The published maximum static pressure is 0.090 inH2O, equivalent to approximately 22.4 Pa.

What bearing system does HA40101V4-000U-C99 use?
The fan uses SUNON's Vapo bearing system and belongs to the MagLev HA series. The bearing type is identified in the exact-model DigiKey specifications.

What is the acoustical noise level?
The published rating is 15.7 dB(A). Actual noise may vary with supply voltage, airflow restriction, mounting conditions and the surrounding equipment.

How is HA40101V4-000U-C99 electrically connected?
The fan has three wire leads, and DigiKey identifies a speed sensor or tachometer feature. The exact connector, wire colors and tachometer signal pinout should be confirmed before integration. A dedicated PWM control lead is not documented for this configuration.

What should be checked before ordering HA40101V4-000U-C99?
Confirm the full SUNON model number, 12 VDC rated supply, 40 x 40 x 10 mm dimensions, mounting-hole spacing, 5000 RPM speed, 5.4 CFM airflow, Vapo bearing construction, three-wire connection, tachometer interface, lead length and connector requirements. DigiKey classifies this model as obsolete and lists HA40101V4-1000U-G99 as a manufacturer-recommended substitute. Nevertheless, the replacement part number, monitoring signals and mechanical configuration must be checked before substitution.
