The **AMPLA5030Q-R56MT** is a high-performance, surface-mount (SMD) power inductor. It is designed for high-current applications where efficiency and a compact footprint are critical. --- ### 1. Technical Specifications The part number typically follows a specific nomenclature used by manufacturers (often associated with high-current molded power inductors). | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.56 µH (indicated by "R56") | | **Tolerance** | ±20% (indicated by "M") | | **Package Size** | 5030 (approx. 5.0mm x 5.0mm x 3.0mm) | | **Core Material** | Metal Alloy / Magnetic Powder | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Shielding** | Magnetically Shielded (Molded construction) | --- ### 2. Key Electronic Features 1. **Molded Construction:** The inductor is constructed using a metallic powder mold. This design results in a "soft saturation" characteristic, meaning the inductance does not drop abruptly when the current increases, unlike traditional ferrite cores. 2. **Low DCR (DC Resistance):** The internal windings use flat or heavy-gauge wire to minimize resistance, reducing power loss through heat (Joule heating). 3. **High Current Rating:** Due to the R56 (0.56µH) value being relatively low, this part is capable of handling very high saturation currents (Isat) and RMS currents (Irms), often exceeding 10–15 Amperes depending on the specific series rating. 4. **Low EMI:** The molded metal body acts as a natural shield, significantly reducing electromagnetic interference (EMI) leakage compared to unshielded wire-wound inductors. --- ### 3. Typical Applications Inductors with these specifications are standard in modern power management circuits: * **DC-DC Converters:** Used in Buck or Boost converters for voltage regulation. * **GPU/CPU Power Supply:** Providing stable current to high-speed processors in laptops or tablets. * **Automotive Electronics:** (If "Q" stands for AEC-Q200) Used in infotainment or ADAS systems due to high temperature stability. * **Battery Powered Devices:** High efficiency helps extend battery life by reducing energy wasted as heat. --- ### 4.
