The **1306F-R22J** is a surface-mount (SMD) power inductor commonly used in high-frequency power supply circuits. Below is a detailed technical breakdown of this component. --- ## 1. Technical Specifications The part number follows a standard coding convention for power inductors. Here are the core parameters: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.22 µH (Microhenries) | | **Tolerance** | ±5% (indicated by the 'J' suffix) | | **Package Type** | Surface Mount Device (SMD) | | **Core Material** | Ferrite or Metal Composite (Shielded) | | **Size Code** | 1306 (approx. 13mm x 13mm footprint, 6mm height) | --- ## 2. Part Number Breakdown To understand the component better, we can deconstruct the identifier: * **1306**: Represents the physical dimensions. Usually, this means a width/length of roughly **13mm** and a profile height of **6mm**. * **F**: Often denotes the series or manufacturer-specific material type (e.g., Lead-free or Ferrite). * **R22**: The inductance value. "R" acts as a decimal point. **R22 = 0.22 µH**. * **J**: The tolerance code. **J = ±5%**; (K would be ±10%, M would be ±20%). --- ## 3. Key Features and Applications These inductors are designed for high-current environments where low DC resistance (DCR) and high saturation currents are required. ### Key Features * **High Current Handling:** Capable of managing high Amperage without saturating. * **Shielded Construction:** Minimizes Electromagnetic Interference (EMI) with surrounding components. * **Low DCR:** Reduces power loss and heat generation. ### Common Applications 1. **DC-DC Converters:** Used as energy storage elements in buck, boost, or buck-boost regulators. 2. **Voltage Regulator Modules (VRMs):** Found on motherboards and GPU power phases. 3. **Battery Powered Systems:** Ideal for high-efficiency power management in portable electronics. 4. **Telecommunications:** Used in base stations and networking hardware. --- ## 4. Soldering and Handling Since this is an SMD component, it is designed for automated assembly: ```markdown - Recommended Footprint: Standard 1306 pad layout. - Soldering Method: Reflow soldering (Lead-free compatible). - Moisture Sensitivity Level (MSL): Usually MSL 1 (unlimited floor life). ``` ---
