The **HT-6V331MF80N-R2** is a specific part number for a **Surface Mount (SMD) Aluminum Electrolytic Capacitor**. This component is primarily used for power management, filtering, and decoupling in electronic circuits. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor (Hybrid/Standard) | | **Capacitance** | 330 µF (Microfarads) | | **Voltage Rating** | 6.3 VDC (Volts Direct Current) | | **Tolerance** | ±20% (Standard) | | **Case Size (Code)** | F80 (typically 6.3mm diameter x 7.7mm or 8mm height) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Packaging** | Tape & Reel (indicated by -R2 suffix) | --- ### 2. Part Number Breakdown While nomenclature varies slightly by manufacturer (such as Lelon, CapXon, or others following this standard numbering), the code generally follows this logic: * **HT**: Series prefix (often denotes High Temperature or Low Impedance series). * **6V**: Rated Voltage (6.3 Volts). * **331**: Capacitance code ($33 \times 10^1 = 330$ µF). * **M**: Tolerance ($\pm 20\%$). * **F80**: Physical dimensions (Size code for the can). * **R2**: Packaging specification (13" or 7" Reel). --- ### 3. Key Features & Applications #### Features: * **Low ESR:** Designed to handle high ripple currents with minimal energy loss. * **Compact Footprint:** The SMD design allows for automated "Pick and Place" assembly on PCBs. * **Temperature Stability:** Usually rated for operation up to **105°C**, making it suitable for industrial environments. #### Common Applications: 1. **Voltage Smoothing:** Placed after a voltage regulator to provide a steady DC output. 2. **Decoupling:** Filtering out high-frequency noise from power supply lines to protect sensitive ICs. 3. **Consumer Electronics:** Found in motherboards, routers, and power adapters where vertical space is limited. --- ### 4. Precautions for Use * **Polarity:** These are **polarized** components. Installing them backwards will cause gas buildup, leaking, or terminal failure (explosion in extreme cases). * **Reflow Soldering:** As an SMD component, it is designed for reflow ovens. Ensure the thermal profile does not exceed the component's maximum heat rating. * **Voltage Margin:** It is best practice to run the capacitor at 70-80% of its rated voltage (e.g., using a 6.3V cap in a 3.3V or 5V circuit).
