Engineering summary: A 120x120x25mm, 12V high-speed DC axial fan with published 0.80A current, 4400RPM speed, 143.1CFM airflow, dual ball bearing construction, and a 4-pin PWM interface. Controller compatibility must be qualified from the approved interface specification.
| Model / product reference | SXD12025B12HPWM |
|---|---|
| Fan family | High-speed brushless DC axial fan with 4-pin PWM interface |
| Dimensions | 120x120x25mm |
| Rated voltage | 12V DC |
| Published rated current | 0.80A; verify startup demand and host-supply margin on the approved sample |
| Published speed | 4400RPM |
| Published airflow | 143.1CFM nominal free-air value; delivered airflow depends on the system resistance curve |
| Static pressure | No numeric pressure point is asserted here; validate the controlled operating range in the real restriction path |
| Noise | No universal dBA value is asserted here; measure at the intended PWM duty points in the assembled equipment |
| Power reference | Approximately 9.6W from the published 12V and 0.80A rated values; confirm approved tolerances before design release |
| Bearing type | Dual ball bearing construction |
| Control / feedback boundary | 4-pin PWM interface. PWM electrical level, frequency, duty range, minimum-speed behavior, pinout, and any FG feedback behavior must follow the approved interface specification; no behavior is inferred from wire colour |
| Material / flammability | Housing and impeller material grade, including any UL94 classification, must follow the approved production specification; no universal grade is asserted on this page |
| Best-fit buyer intent | 12V servers and controlled thermal systems requiring host-commanded speed management and higher airflow, subject to controller, duty-point, startup, and acoustic validation |
| Manufacturer and quality review | SENSDA ELECTRONICS LIMITED / SXDOOL. ISO 9001:2015 quality-management documentation, OEM/ODM cable and connector requirements, Dynamic Balancing, and 100% End-of-Line Testing can be reviewed against the approved production control plan. |
Model-specific engineering FAQ
Which PWM details must the host-controller engineer confirm before integration?
Confirm the approved pinout, PWM input voltage level, frequency, duty-cycle range, controller ground, minimum-speed or stop behavior, startup behavior, pull-up requirements, and any FG feedback interface. Do not infer electrical behavior from connector shape or wire colour.
What is the difference between the PWM lead and an FG feedback lead?
PWM is the host speed-command input. FG, when present in the approved 4-pin interface, is a rotational feedback output. They serve different electrical functions and must not be interchanged; confirm both against the approved interface drawing.
Does 143.1CFM remain available across every PWM duty point and system resistance?
No. The published airflow is a nominal free-air reference for the listed fan grade. PWM duty changes speed, while the equipment pressure loss sets the operating point; validate airflow, temperatures, current, and noise across the intended control range.
How should fail-safe behavior be tested during PWM sample qualification?
The response to a lost PWM command or feedback signal depends on the approved fan interface and the host control strategy. Define the required fallback speed, alarm threshold, restart logic, and thermal shutdown behavior, then verify them with the actual controller and approved fan sample.
Continue with the DC axial fan family, use the fan selector, review system-airflow application guidance, compare the 12V 0.56A fixed high-speed variant, or submit a model-specific RFQ.
