The **THAH1075-R36** is a high-current, surface-mount (SMD) power inductor, typically manufactured by **Delta Electronics**. It is designed specifically for high-frequency DC-DC converters, such as Voltage Regulator Modules (VRMs) used in servers and high-performance computing. --- ### 1. Technical Specifications The following table highlights the primary electronic characteristics of the THAH1075-R36: | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.36 µH (denoted by "R36") | | **Tolerance** | ±20% (Typical) | | **Saturation Current ($I_{sat}$)** | High (Typically 60A - 90A depending on temp) | | **Heating Current ($I_{rms}$)** | High (Designed for low thermal resistance) | | **DCR (Direct Current Resistance)** | Ultra-low (Typically < 0.30 mΩ) | | **Footprint/Size** | ~10.0 x 7.5 x 7.0 mm | | **Construction** | Metal Alloy / Magnetic Shielded | --- ### 2. Key Electronic Features #### A. Power Density and Efficiency The "R36" (0.36 microhenries) inductance is optimized for fast transient response. Because the **DCR** (internal resistance) is extremely low, it minimizes energy loss as heat, allowing the component to handle massive amounts of current without melting or degrading. #### B. Saturation Characteristics Unlike standard inductors that lose their properties quickly when current spikes, the THAH series uses a metal powder core. This provides a **"Soft Saturation"** curve, meaning the inductance drops gradually rather than abruptly when the current increases beyond rated limits. #### C. Shielded Design The part is magnetically shielded. This is critical in modern electronics to prevent **Electromagnetic Interference (EMI)** from leaking into nearby sensitive components, such as CPUs or memory modules. --- ### 3. Common Applications This specific inductor is found in high-demand power environments: * **Server VRMs:** Powering multi-core processors (Intel Xeon, AMD EPYC). * **Graphics Cards (GPU):** Managing power delivery for high-end gaming and AI chips. * **DC/DC Converters:** Used in point-of-load (POL) applications where 12V is stepped down to 1V or less. --- ### 4. Schematic Representation In a circuit diagram, the part is represented as a standard inductor, but its physical implementation requires large copper pads to handle the heat. ```spice * Example Representation in SPICE L1 Node1 Node2 0.36uH .model THAH1075 L(R=0.25m) ; Including DCR ```
