Frequently Asked Questions

What is SUNON EE80251S1-000U-A99?
EE80251S1-000U-A99 is a SUNON EE-series DC brushless axial cooling fan with an 80 x 80 x 25 mm housing, 12 VDC rated supply and lubricated sleeve bearing system.

What is the rated voltage of EE80251S1-000U-A99?
The manufacturer specifies 12 VDC, an operating voltage range of 4.5-13.8 VDC and a starting voltage of 4.5 VDC at 25°C.

What are the dimensions of EE80251S1-000U-A99?
The nominal dimensions are 80 x 80 x 25 mm. The manufacturer drawing specifies an 80 ±0.5 mm square frame, 25 +0.5/-0 mm thickness and 71.5 ±0.3 mm mounting-hole center spacing.

What is the rated current?
The SUNON manufacturer datasheet specifies 145 mA rated current and 167 mA maximum current at the documented operating conditions.

What is the power consumption?
SUNON specifies 1.7 W rated power consumption and 2.0 W maximum power consumption for the exact EE80251S1-000U-A99 model.

What is the rated fan speed?
The manufacturer specifies 3200 RPM with a tolerance of ±10% when operated at the rated supply voltage.

What airflow does EE80251S1-000U-A99 provide?
The published airflow rating is 41 CFM, approximately 69.7 m³/h. Installed airflow depends on enclosure design and resistance in the ventilation path.

What is the maximum static pressure?
The manufacturer specifies 0.18 inH2O, approximately 44.8 Pa. The fan's operating airflow should be evaluated against the resistance characteristics of the equipment being cooled.

What bearing system does EE80251S1-000U-A99 use?
The exact-model SUNON datasheet identifies a lubricated sleeve bearing system. Its published life expectancy reference is 35000 hours at 40°C, 65% relative humidity and 90% confidence level under specified laboratory conditions, rather than an unconditional service-life guarantee.

What is the acoustical noise level?
The published noise rating is 33 dB(A). SUNON describes its acoustic measurement method as operating the fan in free air with a microphone positioned one meter from the fan intake.

How is EE80251S1-000U-A99 electrically connected?
The manufacturer mechanical drawing specifies two UL 1007 24 AWG DC power leads, red positive and black negative, with a 300 ±30 mm lead length. The standard A99 configuration does not provide a separate tachometer or PWM control wire. Automatic restart protection is included, while reverse polarity protection is not identified as included in the manufacturer specification.

What should be checked before ordering EE80251S1-000U-A99?
Confirm the complete SUNON model number, 12 VDC rated supply, 145 mA rated current, 1.7 W rated power, 3200 RPM speed, 41 CFM airflow, 0.18 inH2O static pressure, lubricated sleeve bearing, 80 x 80 x 25 mm housing, 71.5 mm mounting-hole center spacing and two-wire connection. DigiKey identifies the model as obsolete and lists EF80251S1-1000U-A99 as a direct substitute, but mechanical dimensions, electrical characteristics and cooling requirements should still be checked. The related EE80251S1-D170-F99 configuration has different functional wiring and should not automatically be treated as interchangeable.
