The **W2CE-143-R** is a specific part number belonging to the **W2CE series** of high-performance power inductors, typically manufactured by companies like **ITG Electronics**. These components are specifically designed for high-frequency DC-DC converters and voltage regulator modules (VRMs). --- ### 1. Technical Specifications The part number "W2CE-143-R" can be broken down into specific electrical and physical characteristics: | Parameter | Estimated Value / Description | | :--- | :--- | | **Component Type** | High Current Power Inductor | | **Inductance** | 143 nH (Nanohenries) | | **Tolerance** | Typically ±10% or ±20% | | **Saturation Current (Isat)** | High (Usually >50A depending on specific housing) | | **DC Resistance (DCR)** | Ultra-low (Typically <0.5 mΩ) | | **Mounting Type** | Surface Mount (SMD) | | **Construction** | Ferrite Core with Flat Wire or Plate winding | --- ### 2. Key Features * **Low DCR:** The "W2CE" series is known for extremely low direct current resistance. This minimizes power loss and heat generation, which is critical for efficiency in modern computing power stages. * **High Saturation:** These inductors are engineered to handle massive current spikes without the magnetic core "saturating" (losing its inductive properties). * **Compact Footprint:** Designed for high-density PCB layouts found in servers and high-end workstations. * **RoHS Compliant:** The "-R" suffix usually denotes compliance with RoHS (Restriction of Hazardous Substances) standards. --- ### 3. Common Applications The W2CE-143-R is primarily used in the following electronic environments: 1. **Server Power Supplies:** Used in multi-phase buck converters to provide stable voltage to CPUs and GPUs. 2. **Voltage Regulator Modules (VRM):** Critical for stepping down high voltage to the sub-1V levels required by microprocessors. 3. **Data Centers:** High-efficiency power distribution units. 4. **Graphics Cards:** Powering high-performance memory and core processors. --- ### 4. Comparison with Standard Inductors Unlike standard wire-wound inductors used in general electronics, the W2CE series utilizes a **molded or plate-based construction**. ```markdown Comparison Table: | Feature | Standard Inductor | W2CE-143-R | | :--- | :--- | :--- | | Current Handling | Low to Medium | Very High | | Frequency Range | Low | High Frequency (MHz) | | Core Material | Iron Powder / Ferrite | Advanced Low-Loss Ferrite | ``` ---
