The part number **RVG-10V331MG10UN-R2** refers to a specific Surface Mount (SMD) Aluminum Electrolytic Capacitor, typically manufactured by companies like **Elna** or following their standard naming conventions. Below is the technical breakdown of the electronic specifications and characteristics for this component. --- ### 1. Technical Specifications Table | Parameter | Specification | Details | | :--- | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | Polarized storage component | | **Mounting Type** | SMD (Surface Mount Device) | "Chip" type vertical mount | | **Capacitance** | 330 µF | Indicated by "331" (33 x 10^1) | | **Rated Voltage** | 10V DC | Maximum continuous operating voltage | | **Tolerance** | ±20% (M) | Standard industry tolerance | | **Temperature Rating** | -40°C to +105°C | Rated for high-temperature environments | | **Case Size (DxL)** | 8.0 x 10.0 mm (approx.) | "G10" usually denotes the size code | | **Series** | RVG | High reliability / Low impedance series | --- ### 2. Part Number Decoder To understand how the specifications are derived, here is the breakdown of the string: * **RVG**: The **Series Name**. This usually identifies the specific performance tier (e.g., low ESR, long life, or high temperature). * **10V**: The **Rated Voltage** (10 Volts). * **331**: The **Capacitance Code**. The first two digits (33) are the value, and the third (1) is the multiplier. $33 \times 10^1 = 330$ µF. * **M**: The **Tolerance Code**. M stands for ±20%. * **G10**: The **Case Size Code**. This maps to physical dimensions (Diameter x Height) in the manufacturer's datasheet. * **UN**: Often refers to **Packaging or specialized coating** (e.g., lead-free, RoHS compliant). * **R2**: **Taping/Reel Specification**. Indicates the part is supplied on a carrier tape for automated pick-and-place machines. --- ### 3. Key Applications Because this is an **RVG series** (typically low impedance and 105°C rated), it is commonly used in: 1. **Power Supply Filtering:** Smoothing output ripples in DC-DC converters. 2. **Bypass/Decoupling:** Providing a local energy reservoir for integrated circuits. 3. **Consumer Electronics:** Used in laptops, tablets, and telecommunications equipment where space is limited. 4. **Automotive Infotainment:** Suitable for non-safety critical electronic modules due to its 105°C rating. ### 4. Important Usage Notes > [!WARNING] > **Polarity:** This is a polarized component. Ensure the negative stripe on the top of the capacitor aligns with the negative marking on the PCB (usually a shaded area). Reverse voltage will cause the part to overheat or fail catastrophically.
