| Signal / wiring | No control or feedback option is asserted by the base H page; confirm any PWM, FG or RD suffix separately. |
| Operation / storage environment | -10C to 70C, 35%-85% RH operation; -40C to 80C, 35%-85% RH storage per catalog general specification |
| Best-fit buyer intent | Dense 12V power electronics, servers and industrial equipment requiring high free-air and pressure capability. |
| 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. |
Configuration and qualification table
| Verification layer | Current reference | Production-release requirement |
|---|---|---|
| Catalog data layer | SXD12038H catalog grade | Use for initial engineering comparison under catalog test conditions |
| Product definition layer | Complete model and approved drawing | Controls voltage, bearing, cable, connector, signal, rotation, airflow direction and label |
| Application validation layer | 12V high-speed equipment sample | Controls thermal, airflow/pressure, current, vibration, noise and restart approval |
Engineering release rule: Catalog and current-page values are reference data under their stated conditions. The approved drawing, complete model suffix, controlled datasheet, sample label and validated equipment test govern the final purchasable configuration.
Model-specific engineering FAQ
What supply margin is needed around the 3.30A catalog rating?
Use 3.30A only as the rated reference, then measure startup current, harness drop and transient behavior. The connector, PCB trace and supply must tolerate the approved worst case.
Why is 34.6mmH2O pressure important for dense equipment?
A higher pressure capability helps maintain airflow through restrictive heat sinks, filters and narrow passages, but the delivered point still depends on the complete system curve.
What acoustic risk accompanies the 5000RPM H grade?
The catalog reference is 65dBA under its stated measurement condition. Grilles, turbulence and mounting resonance can change the equipment result, so enclosure-level noise and vibration testing are required.
Which thermal test proves that the H grade is necessary instead of the M grade?
Run both approved samples at worst-case ambient and load, then compare critical temperatures, airflow or pressure, current and noise. Use H only when M cannot meet the validated margin.
