### 2. Electrical Characteristics
These fans are designed to operate directly from mains power without the need for an external DC converter.
* **Current Consumption:** Usually ranges between **0.08A to 0.12A**.
* **Protection:** Most models in this series include **Impedance Protection**, meaning the motor coil is designed to resist burning out even if the fan blades are physically locked (stalled).
* **Termination:** Typically features two lead wires (Red/Black or Black/Black) or terminal lugs for quick connection.

### 4. Key Electronic Components
Inside the housing, the fan consists of:
1. **Stator Coils:** Copper windings that create the electromagnetic field.
2. **Permanent Magnet:** Located within the hub of the plastic impeller.
3. **Capacitor (Internal):** Used for phase shifting in AC motors to ensure the fan starts spinning in the correct direction.
4. **Ball Bearings:** Two high-precision bearings that reduce friction and allow for vertical or horizontal mounting.
