The **MAH25TAA-R** is a specific electronic component, typically categorized as a **Micro-Blower** or ultra-compact high-pressure air pump. These are frequently manufactured by companies like **Murata** and are designed for applications requiring precise airflow in a very small footprint. --- ### 1. Technical Specifications The following table outlines the typical electrical and mechanical characteristics for this series: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | Piezoelectric Micro-blower | | **Operating Voltage** | 10V to 20V (p-p) | | **Frequency** | ~25 kHz (Ultrasonic range) | | **Max Air Pressure** | 1.0 kPa to 2.0 kPa | | **Max Flow Rate** | ~0.8 to 1.0 L/min | | **Interface** | SMT (Surface Mount Technology) or Lead wire | | **Dimensions** | Approx. 20mm x 20mm x 2mm | --- ### 2. Core Working Principle The MAH25TAA-R operates on the **Piezoelectric Effect**. Unlike traditional fans that use electromagnetic motors and rotating blades, this part functions as follows: 1. **Piezoelectric Ceramic:** A ceramic element inside the casing vibrates at a high frequency (ultrasonic) when an AC voltage is applied. 2. **Diaphragm Displacement:** This vibration causes a small diaphragm to move up and down, acting like a tiny bellows. 3. **Pressure Generation:** The rapid oscillation creates high static pressure and pushes air through a discharge port. 4. **Silent Operation:** Because the frequency is above the human hearing range (25 kHz), the device is virtually silent. --- ### 3. Key Electronic Features * **Low Power Consumption:** Since it uses a piezoelectric driver, it consumes significantly less power than a DC motor fan. * **No Electromagnetic Interference (EMI):** It does not use magnets or coils, making it ideal for sensitive medical or communication devices. * **Extremely Slim Profile:** Its height is usually under 3mm, allowing it to be integrated into wearable technology. --- ### 4. Common Applications * **Gas Sensors:** Pulling air across a sensor for CO2 or VOC monitoring. * **Medical Devices:** Used in portable oxygen concentrators or diagnostic equipment. * **Aromatherapy/Fragrance:** Micro-diffusers for controlled scent release. * **Cooling:** Spot cooling for small microprocessors in tight enclosures. ---
