The **SWDY0806-R80MF-NC** is a high-performance **SMD (Surface Mount Device) Power Inductor**. It is typically used in DC-DC converters and power management modules where high efficiency and high current handling are required. --- ### 1. Part Number Breakdown While naming conventions vary slightly by manufacturer (often associated with brands like Sunlord or similar power component specialists), the nomenclature generally follows this logic: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **SWDY** | Series Name | Wire-wound shielded power inductor series. | | **0806** | Case Size | Dimensions (approx. 8.0mm x 6.0mm). | | **R80** | Inductance Value | **0.80 µH** (R denotes the decimal point). | | **M** | Tolerance | **±20%** (Standard for power inductors). | | **F** | Material/Feature | Often denotes Ferrite core or Lead-Free status. | | **NC** | Special Code | Usually indicates "No Connection" or specific termination finish. | --- ### 2. Key Technical Specifications Below are the estimated technical parameters for this specific component class: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.80 µH | | **Tolerance** | ±20% | | **DCR (Direct Current Resistance)** | Very Low (typically < 10 mΩ) | | **Saturation Current (Isat)** | High (often 10A - 20A range depending on height) | | **Operating Temperature** | -40°C to +125°C | | **Shielding** | Magnetic Resin Shielded (Semi-shielded) | --- ### 3. Structural Features 1. **Magnetic Shielding:** The "SWDY" series usually features a metallic/ferrite resin coating over the wire windings. This reduces EMI (Electromagnetic Interference) and prevents the inductor from affecting nearby components. 2. **Compact Footprint:** The 0806 size is optimized for high-density PCB layouts in portable electronics. 3. **Low Profile:** Designed to be thin enough for modern smartphone or laptop internal assemblies. --- ### 4. Common Applications * **DC-DC Converters:** Used as the energy storage element in buck, boost, or buck-boost regulators. * **Power Supplies:** Common in laptop motherboards and server power rails. * **Consumer Electronics:** High-current stages in smartphones, tablets, and gaming consoles. * **LED Drivers:** Used to smooth current for high-brightness LED arrays. ---
