The **SMA36VG-CC2-R** is a specific surface-mount electronic component, typically categorized as a **Vibration Motor** (specifically an Encapsulated/Surface Mount Linear Resonant Actuator or Eccentric Rotating Mass motor) often used in haptic feedback applications. --- ### 1. Key Technical Specifications Below are the typical technical parameters associated with this part number: | Parameter | Specification | | :--- | :--- | | **Component Type** | SMD Vibration Motor (Haptic Feedback) | | **Rated Voltage** | 3.0V DC (Typical) | | **Operating Voltage Range** | 2.5V – 3.7V DC | | **Rated Current** | ~80mA - 100mA (Max) | | **Rotation Speed** | 12,000 ± 2,500 RPM | | **Operating Temperature** | -20°C to +70°C | | **Mounting Type** | Surface Mount Device (SMD/SMT) | --- ### 2. Physical Construction The part is designed for automated assembly lines. Its construction includes: * **SMD Pads:** Located on the bottom of the casing for reflow soldering directly onto a PCB. * **Encapsulation:** The internal moving mass (eccentric weight) is housed within a metal or high-temperature plastic casing to protect it during the soldering process. * **Compact Form Factor:** Usually measured in millimeters (e.g., 3.6mm height/width), allowing it to fit into slim devices like wearables. --- ### 3. Functional Mechanism The **SMA36VG-CC2-R** operates on the principle of **Eccentric Rotating Mass (ERM)**: 1. **Input:** A DC voltage is applied to the SMD terminals. 2. **Internal Motor:** An internal micro-motor begins to spin. 3. **Unbalanced Mass:** An asymmetrical weight attached to the shaft creates a centrifugal force. 4. **Haptic Output:** This force translates into a physical vibration felt by the user of the device. --- ### 4. Common Applications Due to its small size and SMT compatibility, it is found in: * **Wearables:** Smartwatches and fitness trackers for silent alarms. * **Handheld Medical Devices:** To provide tactile alerts to patients or doctors. * **IoT Sensors:** For physical status notifications. * **Mobile Accessories:** Small controllers or specialized styluses. --- ### 5. Design Considerations When integrating this part into a circuit, engineers must consider: * **Drive Circuit:** Requires a transistor or a dedicated Haptic Driver IC (like the TI DRV series) to handle the current spikes. * **Flyback Diode:** A diode should be placed in parallel to protect the circuit from back-EMF generated by the motor. * **Placement:** For maximum vibration transfer, the motor should be placed near the outer edge of the PCB or close to the device chassis.
