The **MPV3J10B8QJ-R** is a high-performance, molded power inductor manufactured by **Cyntec**. It is designed specifically for high-density power applications such as DC-DC converters in laptops, servers, and automotive infotainment systems. --- ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Inductance** | 1.0 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | ~18.5 mΩ (Typ) / 20.4 mΩ (Max) | | **Saturation Current (Isat)** | ~8.0 A (Approximate) | | **Heating Current (Irms)** | ~6.5 A (Approximate) | | **Dimensions** | 3.2 x 2.5 x 1.0 mm (approx. size code 3225) | | **Operating Temperature** | -55°C to +125°C | --- ## Key Features & Construction ### 1. Metal Alloy Core Unlike traditional ferrite inductors, this part uses a **metal alloy powder** core. This provides a "soft saturation" characteristic, meaning the inductance drops gradually as current increases rather than dropping off sharply. ### 2. Molded Construction The coil is embedded directly into the metal powder body under high pressure. This results in: * **Low Acoustic Noise:** Minimizes "coil whine" caused by magnetostriction. * **Magnetic Shielding:** Naturally reduces Electromagnetic Interference (EMI) to surrounding components. * **Ruggedness:** Excellent resistance to mechanical shock and vibration. ### 3. Low Profile (Thin Design) The "10" in the part number often signifies a max height of **1.0 mm**. This makes it ideal for ultra-thin electronics like tablets and thin-and-light laptops. --- ## Typical Applications * **Voltage Regulator Modules (VRM):** Used in CPU and GPU power delivery. * **Point of Load (POL) Converters:** Step-down conversion for various board-level voltages. * **Handheld Devices:** Smart phones and tablets where space is a premium. * **Automotive:** Infotainment and ADAS systems (where AEC-Q200 qualification is present). --- ## Marking and Packaging The **"-R"** suffix typically indicates that the parts are supplied on a **Tape and Reel** for use with automated Pick-and-Place SMT (Surface Mount Technology) assembly lines.
