The **MAH22FAA-R** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor**. These parts are essential in power management circuits for filtering, energy storage, and noise suppression. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The "MAH" series is generally manufactured by companies like **ABC Taiwan Electronics** or similar specialized inductor manufacturers. These are designed for high-density surface mount applications. | Feature | Description | | :--- | :--- | | **Component Type** | Fixed Inductor / Power Inductor | | **Construction** | Shielded (Magnetic) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Packaging** | Tape & Reel (indicated by the "-R") | --- ### 2. Electrical Characteristics While specific values can vary slightly by manufacturer batch, the "22" in the part number typically refers to the inductance value. * **Inductance:** 22.0 µH (Microhenries). * **Tolerance:** Usually ±20% (Standard for power inductors). * **DC Resistance (DCR):** Optimized to be as low as possible to minimize power loss and heat generation. * **Saturation Current:** The maximum current at which the inductance drops by a specified percentage (usually 30%). * **Shielding:** Being a shielded inductor, it confines the magnetic flux, reducing Electromagnetic Interference (EMI) with neighboring components. --- ### 3. Applications The MAH22FAA-R is commonly found in the following electronic environments: 1. **DC-DC Converters:** Used as energy storage elements in buck or boost regulators. 2. **Portable Electronics:** Smartphones, tablets, and laptops due to its low profile. 3. **Power Supplies:** Filtering high-frequency noise in switching power supplies. 4. **Consumer Electronics:** LED drivers and battery-powered devices. --- ### 4. Key Advantages * **Compact Size:** Designed for automated assembly on PCBs where space is limited. * **Low EMI:** The magnetic shielding makes it suitable for high-density boards where cross-talk must be avoided. * **High Reliability:** Built to withstand standard reflow soldering temperatures. ---
