The **M5R75TPJ-R** is a high-performance, shielded power inductor typically manufactured by companies like **ITG Electronics**. It is designed for high-current applications, particularly in multi-phase voltage regulator modules (VRMs). --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the typical technical parameters: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | ~75 nH (Nanohenries) | | **Tolerance** | ±10% to ±20% | | **DCR (DC Resistance)** | Very Low (typically < 0.3 mΩ) | | **Isat (Saturation Current)** | High (often 50A - 100A range) | | **Operating Temperature** | -40°C to +125°C | | **Package Type** | Surface Mount (SMD) | --- ### 2. Physical and Material Characteristics * **Shielded Construction:** The part features a magnetic shield (often a ferrite or iron powder composite) to minimize Electromagnetic Interference (EMI) and protect nearby sensitive components from noise. * **Manganese-Zinc (MnZn) Core:** Often utilizes high-frequency ferrite materials to reduce core losses at the high switching frequencies (MHz range) used in modern processors. * **Low DCR Design:** Uses heavy-gauge flat wire or copper plate to minimize power loss through heat (I²R losses), making it extremely efficient. --- ### 3. Common Applications This specific inductor is engineered for high-density power delivery: 1. **Server CPU/GPU Power:** Used in multi-phase VRMs for high-end processors (Intel/AMD) and GPUs (NVIDIA/AMD). 2. **Point of Load (POL) Converters:** High-efficiency DC-DC converters in networking equipment. 3. **Data Centers:** Power supplies requiring high power density and minimal thermal footprint. --- ### 4.
