The **W2SP-1B3-R2** is a specific model within the **W2SP series**, which are high-performance, stackable, and high-density power inductors often used in automotive and industrial applications. These are typically manufactured by specialized magnetic component providers like **ITG Electronics**. --- ## 1. Core Specifications The technical attributes of the W2SP-1B3-R2 focus on handling high currents while maintaining a compact footprint through a unique "stacked" design. | Parameter | Typical Description | | :--- | :--- | | **Component Type** | High Current Power Inductor (SMD) | | **Inductance** | Usually in the range of 150nH to 300nH (Model specific) | | **Current Rating (Irms)** | Very High (Often >50A depending on thermal conditions) | | **Saturation Current (Isat)** | High (designed to avoid core saturation under heavy load) | | **DCR (Resistance)** | Ultra-low (measured in mΩ) to minimize power loss | | **Operating Temp** | -40°C to +125°C or higher | --- ## 2. Key Electronic Features ### A. Stacked Design The "W2SP" prefix often refers to the **Window-type Stacked Power** architecture. Unlike traditional flat inductors, these use a vertical stacking method to: * Reduce the PCB footprint. * Improve thermal dissipation. * Allow for higher current density in multi-phase Voltage Regulator Modules (VRM). ### B. Low DCR (DC Resistance) The internal copper winding is designed with a large cross-sectional area. This results in extremely low resistance, which is critical for: * Increasing efficiency in power conversion. * Reducing heat generation during high-current operations. ### C. Magnetic Shielding The part is typically shielded. This prevents electromagnetic interference (EMI) from leaking out and affecting sensitive neighboring components on the PCB, which is vital for high-frequency switching power supplies. --- ## 3. Typical Applications The W2SP-1B3-R2 is engineered for demanding environments where space is at a premium and power requirements are high: 1. **Server & Data Centers:** Used in VRMs for CPUs and GPUs. 2. **Automotive Electronics:** Powering Advanced Driver Assistance Systems (ADAS) and Infotainment units. 3. **Industrial Computing:** High-load DC-DC converters. 4. **Telecom:** Base station power modules. --- ## 4. Package Dimensions (Generic Example) While specific to the R2 revision, these parts generally follow a standard high-current SMD footprint: ```text Example Footprint: Length: ~10.0 mm Width: ~7.0 mm Height: ~10.0 mm (Stacked height is usually the defining feature) ```
