The **RVR-6V331MF80UN-R2** is a surface-mount (SMD) Aluminum Electrolytic Capacitor. This specific part belongs to a high-reliability, low-impedance series often used in power management and filtering circuits. Below is a detailed breakdown of its specifications and electronic characteristics. ### 1. Technical Specifications | Parameter | Value | Description | | :--- | :--- | :--- | | **Capacitance** | 330 $\mu$F | Charge storage capacity | | **Voltage Rating** | 6.3 VDC | Maximum operating DC voltage | | **Tolerance** | $\pm$20% | Allowable deviation in capacitance | | **Temperature Range** | -55°C to +105°C | Operating thermal limits | | **Endurance** | 2,000 Hours | Life span at maximum rated temperature | | **Mounting Type** | SMD (Chip) | Surface Mount Device | | **Dimensions** | 6.3 x 7.7 mm | Diameter x Height (Case Size F80) | --- ### 2. Key Features and Construction * **Low Impedance:** This part is designed for high-frequency applications. Low impedance (or ESR) ensures minimal energy loss and heat generation during operation. * **Vertical Chip Type:** The "V" in the series name typically refers to a vertical chip design, which saves horizontal board space (footprint) while providing stable mechanical mounting for reflow soldering. * **Polarity:** As an Aluminum Electrolytic capacitor, it is **polarized**. The negative terminal is usually marked with a black stripe on the top of the casing. --- ### 3. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer (like ELNA or Samyoung), the code generally breaks down as follows: * **RVR:** Series Code (High reliability/Low impedance). * **6V:** Rated Voltage (6.3 Volts). * **331:** Capacitance Code (33 followed by one zero = 330$\mu$F). * **M:** Tolerance ($\pm$20%). * **F80:** Case Size Code (Refers to the 6.3mm diameter). * **UN-R2:** Packaging/Lead Tape suffix (Reel packaging for automated assembly). --- ### 4. Common Applications Due to its high capacitance and low voltage, this part is ideal for: 1. **Smoothing:** Filtering noise out of DC-DC converter outputs. 2. **Bypassing:** Providing a local energy reservoir for integrated circuits (ICs). 3. **Consumer Electronics:** Used in laptops, motherboards, and digital peripherals where space is limited but high capacitance is required. ---
