The **SSL1208-R44MF** is an electronic component primarily categorized as a **High-Current Power Inductor**. It is designed for high-density surface mount (SMD) applications where high efficiency and high saturation current are required. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers (typically Pulse Electronics or similar magnetic component vendors). Below are the standard specifications for this part: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.44 µH (indicated by "R44") | | **Tolerance** | ±20% (typically) | | **Case Size** | 1208 (approx. 12.0 x 12.0 x 8.0 mm) | | **DCR (Direct Current Resistance)** | Extremely low (typically < 1.0 mΩ) | | **Saturation Current (Isat)** | Very High (often > 40A to 60A) | | **Temperature Range** | -40°C to +125°C | --- ### 2. Core Features * **Magnetically Shielded:** The construction minimizes Electromagnetic Interference (EMI), making it suitable for noise-sensitive circuits. * **Low DCR:** The use of flat wire or heavy-gauge copper ensures minimal power loss through heat, maximizing energy efficiency. * **High Saturation:** It can handle high peak currents without the inductance dropping significantly, which is critical for stable power delivery. * **SMD Design:** Optimized for automated pick-and-place assembly. --- ### 3. Common Applications This inductor is typically found in high-performance power management stages: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery on motherboards and servers. 2. **DC-DC Converters:** High-frequency buck converters or step-down regulators. 3. **Industrial Power Supplies:** Used in high-current distributed power systems. 4. **Automotive Electronics:** Powering infotainment or ADAS systems (if AEC-Q200 qualified). --- ### 4. Part Number Breakdown Understanding the code helps in identifying replacements: * **SSL:** Series identifier (Shielded Smart Inductor / Power series). * **1208:** Physical dimensions (roughly 12mm x 12mm width/length and 8mm height). * **R44:** Inductance value ($0.44$ microhenries). * **M:** Tolerance code ($M = \pm 20\%$). * **F:** Lead-free / RoHS compliant finish.
