The **1306F-R10J** is a high-current, surface-mount (SMD) power inductor commonly used in DC-DC converters and high-frequency power supplies. This specific part number typically refers to a molded power inductor produced by manufacturers like **Bourns** or similar magnetic component specialists. --- ### 1. Technical Specifications Below are the primary technical characteristics associated with this component: | Parameter | Value/Description | | :--- | :--- | | **Inductance** | 0.10 µH (Microhenries) | | **Tolerance** | ±5% (indicated by the 'J' suffix) | | **Mounting Type** | Surface Mount (SMD) | | **DCR (DC Resistance)** | Very Low (typically < 1.0 mΩ) | | **Current Rating** | High (often 30A to 60A depending on package) | | **Core Material** | Carbonyl Iron / Magnetic Metal Powder | | **Operating Temp** | -40°C to +125°C | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the component's construction: * **1306**: Refers to the physical dimensions. Usually, this means approximately **13mm x 13mm** with a height of around **6mm**. * **F**: Often denotes a specific series type or material (e.g., Lead-free or specific frequency optimization). * **R10**: Represents the inductance value. The "R" acts as a decimal point. **R10 = 0.10 µH**. * **J**: Represents the tolerance. **J = ±5%**. --- ### 3. Key Features and Applications #### Features: * **High Saturation Current:** Designed to handle high current spikes without the magnetic core "saturating" (losing its inductive properties). * **Low Profiles:** Despite high power handling, the 1306 footprint remains relatively compact for PCB designs. * **Shielded Construction:** Most molded inductors are shielded, meaning they have low EMI (Electromagnetic Interference) leakage. #### Common Applications: 1. **Voltage Regulator Modules (VRMs):** Found on motherboards and server cards to regulate CPU/GPU power. 2. **DC-DC Converters:** Used in point-of-load (POL) power supplies. 3. **Battery Powered Systems:** Ideal for high-efficiency power management in portable devices. 4. **Automotive Electronics:** Used in infotainment and driver assistance systems due to high-temperature stability. --- ### 4. Selection Considerations When replacing or designing with the 1306F-R10J, consider these factors: * **Saturation Current ($I_{sat}$):** Ensure the peak circuit current does not exceed the inductor's saturation point. * **Heating Current ($I_{rms}$):** Ensure the continuous current does not cause the component to exceed its maximum operating temperature. * **Pad Layout:** Verify the footprint (land pattern) matches the specific manufacturer's datasheet, as small variations exist between brands. ---
