The part number **10VF2-GA0-R** typically refers to a high-performance **Surface Mount Device (SMD) Power Inductor**, often manufactured by companies like Sumida or similar magnetic component specialists. These components are critical for power management circuits. --- ### 1. Technical Specifications Below is a breakdown of the typical specifications for this series of power inductors: | Feature | Specification | | :--- | :--- | | **Component Type** | SMD Power Inductor (Shielded) | | **Inductance Range** | Varies by sub-code (typically 1.0µH to 10µH) | | **Tolerance** | Usually ±20% (M) or ±30% (N) | | **Core Material** | Ferrite / Metal Composite | | **Mounting Type** | Surface Mount (SMT) | | **Operating Temp** | -40°C to +125°C (including self-heating) | | **Shielding** | Magnetically shielded for low EMI | --- ### 2. Key Characteristics The **10VF2-GA0-R** is designed for high-efficiency power conversion. Key traits include: * **Low DC Resistance (DCR):** Minimizes power loss as heat, increasing overall battery life in portable devices. * **High Saturation Current:** The "GA0" series often features high $I_{sat}$ ratings, meaning the inductor maintains its inductance even under high current loads. * **Compact Footprint:** The "10" in the prefix usually denotes a specific case size (e.g., approximately 10mm x 10mm), though exact dimensions should be verified in the specific manufacturer's datasheet. * **RoHS Compliant:** The "-R" suffix generally indicates compliance with environmental regulations (Lead-free/RoHS). --- ### 3. Common Applications These inductors are found in circuits where stable voltage regulation is required: 1. **DC-DC Converters:** Used in "Buck" (step-down) or "Boost" (step-up) converters. 2. **Point of Load (POL):** Supplying power to CPUs, GPUs, and FPGAs on motherboards. 3. **Consumer Electronics:** Laptops, tablets, and high-end gaming consoles. 4. **Automotive:** Infotainment systems and ADAS modules (if AEC-Q200 qualified). --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, here is a general logical map: * **10V:** Refers to the physical dimensions/series type. * **F2:** Internal design code or core material type. * **GA0:** Specific electrical characteristics (Inductance value/tolerance). * **-R:** RoHS compliance / Tape & Reel packaging.
