The **AIAM-02-R22M** is a high-performance molded miniature power inductor designed for Surface Mount Technology (SMT). It is commonly used in power management circuits to provide stable inductance and high current handling in a compact form factor. --- ### 1. General Specifications Below are the primary technical characteristics of the AIAM-02-R22M: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.22 µH | | **Tolerance** | ±20% (indicated by 'M' suffix) | | **DC Resistance (DCR)** | 0.015 Ω (Max) | | **Rated Current (I-rms)** | ~2.6 A to 3.0 A (Depending on temperature rise) | | **Self-Resonant Frequency (SRF)** | >200 MHz | | **Package Type** | Molded Shielded (SMD) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Key Components & Construction The "AIAM" series utilizes specific materials and construction methods to ensure reliability: * **Core Material:** Usually a high-saturation powdered iron or composite core. This allows the inductor to handle peak currents without the inductance dropping off sharply (soft saturation). * **Molded Shielding:** The coil is encapsulated in a magnetic metal powder resin. This provides **magnetic shielding**, which minimizes Electromagnetic Interference (EMI) with neighboring components on the PCB. * **Terminations:** Features robust solderable pads (usually tin-plated) designed for high-speed automated pick-and-place assembly. --- ### 3. Part Number Breakdown The part number can be decoded as follows: 1. **AIAM-02:** The series name and physical size/form factor (standardized dimensions). 2. **R22:** The inductance value. "R" represents the decimal point; therefore, R22 = **0.22 µH**. 3. **M:** The tolerance code. M stands for **±20%**. --- ### 4. Typical Applications Because of its low DCR and small footprint, this part is ideal for: * **DC/DC Converters:** Used as an output filter inductor in buck/boost regulators. * **Smartphones & Tablets:** High-density power modules where space is limited. * **Laptops/PCs:** Powering CPU/GPU voltage regulator modules (VRM). * **Noise Suppression:** Filtering high-frequency noise in power supply lines. --- ### 5. Footprint (Mechanical Dimensions) *While dimensions can vary slightly by manufacturer (e.g., Abracon), the "02" series typically follows these approximate dimensions:* ```text Length: 2.5 mm Width: 2.0 mm Height: 1.2 mm (Low profile) ```
