## Overview of MA2HTAD-R The **MA2HTAD-R** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor**. It is part of the MA series often manufactured by companies like **Cyntec** or similar electronic component providers. These inductors are designed for high-efficiency power conversion in compact electronic devices. --- ### Technical Specifications Below are the general characteristics and technical parameters for this type of component: | Feature | Description | | :--- | :--- | | **Component Type** | Power Inductor (Molded Type) | | **Inductance Range** | Typically low (e.g., 0.22µH to 2.2µH depending on exact sub-variation) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Construction** | Metal alloy powder (Molded) | | **Shielding** | Magnetically Shielded (Low EMI) | | **Operating Temp** | -40°C to +125°C | --- ### Key Internal Parts and Material Composition The "Electronic Parts" within the MA2HTAD-R construction include: 1. **Magnetic Core (Metal Powder):** The body is made of a molded metal alloy powder. This provides a "soft saturation" characteristic, meaning the inductance decreases gradually as current increases, rather than dropping off sharply. 2. **Copper Coil:** Inside the molded body is a high-conductivity copper wire wound to specific turns. The thickness of this wire determines the **DCR** (Direct Current Resistance) and the current handling capability. 3. **Terminations (Electrodes):** The bottom of the part features lead-free terminations (usually Sn/Tin plated) designed for reflow soldering onto a PCB. 4. **Epoxy/Resin Binder:** A high-temperature resin is used to bind the metal powder and protect the internal coil from environmental factors like moisture and vibration. --- ### Applications Due to its small footprint and high current handling, it is commonly used in: * **DC-DC Converters:** Voltage regulation in smartphones and tablets. * **CPU/GPU Power:** Localized power delivery on motherboards. * **Wearables:** Devices requiring ultra-thin components. --- ### Identification Example When reading the part number `MA2HTAD-R`, the breakdown is usually: * **MA:** Series Name (Molded Power Inductor). * **2H:** Size Code (e.g., 2.5mm x 2.0mm). * **T:** Packaging (Tape and Reel). * **AD:** Material/Design revision code. * **R:** Specific inductance or tolerance indicator.
