The **P7600-R68M** is a high-performance **Shielded Power Inductor**, commonly used in DC-DC converter applications and power management modules. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications The part number follows a standard nomenclature used by manufacturers (such as Cyntec or similar power component specialists). | Feature | Description | | :--- | :--- | | **Component Type** | Fixed Inductor / Power Choke | | **Inductance** | 0.68 µH (indicated by "R68") | | **Tolerance** | ±20% (indicated by "M") | | **Construction** | Metal Alloy / Molded Shielded | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Technical Characteristics As a high-current inductor, it is designed for efficiency and stability under load. * **Saturation Current ($I_{sat}$):** This is the current level where the inductance drops by a specific percentage (usually 20-30%). For a 0.68µH inductor in this size class, $I_{sat}$ is typically very high (often exceeding 20A-30A depending on the specific series). * **Heating Current ($I_{rms}$):** The continuous current that causes a specific temperature rise (usually 40°C). * **Low DCR (DC Resistance):** These parts are designed with very low resistance to minimize power loss and heat generation ($P = I^2R$). * **Shielding:** The molded construction provides magnetic shielding, which reduces Electromagnetic Interference (EMI) with surrounding components. --- ### 3. Application Areas The P7600-R68M is typically found in high-frequency switching environments: 1. **Voltage Regulator Modules (VRM):** Used in CPU and GPU power supplies on motherboards. 2. **Point of Load (POL) Converters:** For step-down (Buck) conversion in telecommunications and servers. 3. **Battery Powered Devices:** High efficiency makes it suitable for laptop and tablet power rails. 4. **Automotive Electronics:** If qualified, it is used in ADAS or infotainment power systems due to its robust molded construction. --- ### 4. Physical Dimensions (Typical) While "7600" often refers to the series or footprint, it usually corresponds to a standardized metric or imperial package size (roughly **7.0 x 6.5 mm** or similar). | Dimension | Typical Measurement | | :--- | :--- | | **Length** | ~ 7.0 mm | | **Width** | ~ 6.6 mm | | **Height** | ~ 3.0 - 5.0 mm |
