The part number **0V2-R56-R** refers to a specific type of **Surface Mount (SMD) Power Inductor**. These components are critical in power management circuits for energy storage and filtering. ### 1. Technical Specifications Based on the industry-standard nomenclature for the "0V2" and "R56" series (commonly produced by manufacturers like Coiltronics/Eaton), the specifications are generally as follows: | Feature | Specification | Description | | :--- | :--- | :--- | | **Inductance** | 0.56 µH (Microhenries) | Indicated by "R56" (R acts as a decimal) | | **Tolerance** | ±20% | Standard for power inductors | | **Part Series** | FP0705 or similar | High-frequency, high-current series | | **DCR (Resistance)** | Very Low | Designed to minimize power loss | | **Mounting Type** | SMD/SMT | Surface mount technology | | **RoHS Status** | Compliant | Indicated by the suffix "-R" | --- ### 2. Breakdown of the Part Number * **0V2**: This often designates the specific product family or a variation in the physical size/core material of the inductor. * **R56**: The value code. The 'R' represents the decimal point. Thus, $0.56$ microhenries ($\mu H$). * **-R**: Typically signifies that the part is **RoHS compliant** (lead-free) and supplied on a tape-and-reel for automated assembly. --- ### 3. Common Applications These inductors are "high-current" components, meaning they are built to handle significant amperage without saturating. You will typically find them in: * **DC-DC Converters:** Voltage regulator modules (VRMs) for CPUs and GPUs. * **Power Supplies:** Used in laptop motherboards and servers. * **Filtering:** Reducing electromagnetic interference (EMI) and smoothing out current ripples in high-speed switching circuits. --- ### 4. Physical Characteristics * **Core Material:** Usually a Ferrite core which offers high efficiency at high switching frequencies. * **Construction:** Usually a shielded design to prevent magnetic interference with surrounding components on the PCB.
