The **MP220G-R10-F** is a specific electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor**. These parts are critical in power management circuits, specifically for DC-DC converters and voltage regulators. --- ### 1. General Specifications Based on the part numbering convention commonly used by manufacturers like **Micro Power (MP)** or similar magnetic component producers, here are the technical characteristics: | Parameter | Estimated Value / Description | | :--- | :--- | | **Component Type** | Power Inductor (Shielded) | | **Inductance Value** | **22.0 µH** (Microhenries) | | **Tolerance** | ±20% (Typical for 'M' or standard codes) | | **Package / Case** | Surface Mount (SMD) | | **Series** | MP220 (High current, low profile) | --- ### 2. Key Features * **Shielded Construction:** The inductor is usually magnetically shielded to prevent Electromagnetic Interference (EMI) with neighboring components on the PCB. * **Low DC Resistance (DCR):** Designed to minimize power loss as heat, ensuring high efficiency in power supplies. * **High Saturation Current:** Engineered to maintain inductance even when high current levels pass through the coil. * **Lead-Free / RoHS Compliant:** The "F" suffix often denotes "Lead-Free" or "Halogen-Free" compliance. --- ### 3. Part Number Breakdown While manufacturer codes vary slightly, the string **MP220G-R10-F** generally decodes as follows: | Segment | Meaning | | :--- | :--- | | **MP** | Manufacturer Series Identifier | | **220** | **Inductance Code:** 220 translates to 22µH (22 followed by 0 zeros). | | **G** | Tolerance or Material Class (G often represents ±2% or a specific core type). | | **R10** | **Size/Revision:** Often refers to the physical footprint (e.g., 10mm x 10mm). | | **F** | **Compliance:** Lead-free / RoHS compliant. | --- ### 4. Typical Applications These inductors are found in the following electronic environments: 1. **Switching Mode Power Supplies (SMPS):** Used for energy storage. 2. **DC-DC Converters:** Buck, Boost, or Buck-Boost topologies. 3. **Laptops and Servers:** Powering CPU/GPU voltage regulator modules (VRMs). 4. **LED Drivers:** Providing constant current for lighting applications. ---
