The **M6SWVS-46-R** refers to a high-performance, shielded power inductor typically manufactured by brands like **Coiltronics (Eaton)**. These components are part of the **M6** or **MPI** series, designed for high-current power conversion applications where space and efficiency are critical. ### 1. Component Overview The M6SWVS-46-R is a surface-mount (SMD) power inductor. Its primary function is to store energy in a magnetic field within DC-DC converter circuits, filtering out noise and stabilizing current flow. --- ### 2. Technical Specifications While exact values can vary slightly by manufacturer batch, the typical characteristics for this series are as follows: | Parameter | Typical Value / Description | | :--- | :--- | | **Inductance** | 4.6 µH (nominal) | | **Tolerance** | ±20% | | **Shielding** | Magnetically Shielded (Low EMI) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Core Material** | Composite Powder (Metal Alloy) | | **Operating Temp** | -40°C to +125°C | --- ### 3. Key Electronic Features * **Magnetically Shielded:** The inductor is enclosed in a magnetic material that minimizes Electromagnetic Interference (EMI). This is vital for densely packed circuit boards where noise can interfere with sensitive components. * **High Saturation Current:** Designed to handle high peak currents without the inductance dropping significantly (saturation). * **Low DCR (DC Resistance):** It uses flat-wire or heavy-gauge copper winding to minimize power loss through heat, leading to higher efficiency in power supplies. * **Rugged Construction:** The "M6" footprint is specifically engineered to handle high-vibration environments and thermal cycling. --- ### 4. Typical Applications These inductors are found in power management stages for: 1. **Voltage Regulator Modules (VRMs):** For CPUs and GPUs. 2. **Point-of-Load (POL) Converters:** Converting a main bus voltage (e.g., 12V) to a lower logic voltage (e.g., 1.8V). 3. **Industrial Electronics:** High-efficiency power supplies for sensors and controllers. 4. **Automotive Infotainment:** Where low EMI and temperature stability are required. --- ### 5.
