The **M5R86XHJ-R** is a specific electronic component identifier typically associated with **Magcom** or similar magnetic component manufacturers. This part is a **Surface Mount Device (SMD) Power Inductor**, commonly used in power management circuits. --- ## Technical Specifications Based on the standard nomenclature for this series, here are the general technical characteristics: | Property | Typical Value / Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Core Material** | Metal Alloy / Carbonyl Iron (High Saturation) | | **Shielding** | Magnetically Shielded (Low EMI) | | **Inductance Range** | Varies by sub-code (typically 0.1µH to 10µH) | | **Package Size** | Approx. 8.0mm x 8.0mm (standard "86" footprint) | --- ## Key Features ### 1. High Saturation Current Because these inductors often use a molded metal powder core, they handle high peak currents without the inductance dropping off sharply. This is critical for preventing circuit failure during power surges. ### 2. Low DC Resistance (DCR) The internal windings are designed to minimize resistance, which reduces power loss as heat and improves the overall efficiency of the power supply. ### 3. Magnetic Shielding The component is fully encapsulated. This prevents magnetic flux from leaking and interfering with nearby sensitive components on the PCB, and it also protects the inductor from external electromagnetic interference (EMI). --- ## Common Applications These parts are found in modern electronics that require compact, efficient power conversion: * **DC-DC Converters:** Step-down (Buck) or Step-up (Boost) regulators. * **Computing:** Motherboards, VRMs (Voltage Regulator Modules), and Graphic Cards. * **Telecommunications:** Network switches and base station power modules. * **Consumer Electronics:** High-end laptops and gaming consoles. --- ## Part Number Breakdown (Generic) While manufacturers vary, the code usually breaks down as follows: * **M5:** Series identifier (Metal Alloy Molded). * **R86:** Physical dimensions (roughly 8.6mm footprint). * **X:** Height or performance variant. * **HJ:** Core material or specific tolerance rating. * **-R:** RoHS compliant (Lead-free).
