Technical Specifications The following table outlines the key electrical and physical characteristics of the HPC104N-R36MTR: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.36 µH | | **Tolerance** | ±20% (M) | | **DC Resistance (DCR)** | ~0.85 mΩ (Typical) / 1.1 mΩ (Max) | | **Saturation Current (Isat)** | ~40A - 50A (Depending on temp rise) | | **Operating Temperature** | -55°C to +125°C (Includes self-heating) | | **Case Size** | 104N (Approx. 11.5 x 10.3 x 4.0 mm) | | **Packaging** | Tape & Reel (TR) | --- ### 2. Key Features and Construction The "HPC" series is engineered for efficiency in demanding environments. * **Shielded Construction:** The inductor is magnetically shielded, which minimizes Electromagnetic Interference (EMI) and prevents the magnetic field from affecting neighboring components on the PCB. * **Metal Alloy Core:** Unlike traditional ferrite cores, these parts often use a metal powder composite core. This allows for a "soft saturation" characteristic, meaning the inductance drops gradually rather than abruptly when current increases. * **Low DCR:** The extremely low DC resistance ensures minimal power loss through heat, which is critical for high-efficiency DC-DC converters. * **AEC-Q200 Compliance:** Most parts in this series are qualified for automotive use, ensuring high reliability under mechanical vibration and thermal shock. --- ### 3. Application Use Cases This component is primarily used in **Voltage Regulator Modules (VRMs)** and **Point of Load (POL)** converters. * **Automotive:** Infotainment systems, ADAS (Advanced Driver Assistance Systems), and LED lighting drivers. * **Computing:** High-current power rails for CPUs, GPUs, and FPGAs. * **Industrial:** High-efficiency switch-mode power supplies (SMPS) and battery-powered devices. --- ### 4. Part Number Breakdown While manufacturer coding can vary slightly, the nomenclature generally follows this logic: * **HPC:** Series Name (High Power Component / Inductor). * **104N:** Physical dimensions (roughly 10x10mm footprint). * **R36:** Inductance value (R represents the decimal point; 0.36 µH). * **M:** Tolerance (M = ±20%). * **TR:** Packaging type (Tape & Reel).
