The **HV-6V331MF80Q-R2** is a specific part number for a Surface Mount (SMT) Aluminum Electrolytic Capacitor, typically manufactured by brands like **Elna** or companies following the same naming convention. Below is the technical breakdown and classification of this electronic component. --- ### 1. Component Overview The device is an electrolytic capacitor designed for high-reliability applications, often featuring a low impedance profile suitable for surface mount technology (SMT) on Printed Circuit Boards (PCBs). | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Capacitance** | 330 µF | | **Voltage Rating** | 6.3V DC | | **Package/Case Size** | 6.3mm x 7.7mm (approx.) | | **Operating Temp** | -40°C to +105°C | --- ### 2. Part Number Breakdown Electronic part numbers are alphanumeric codes where each segment represents a physical or electrical characteristic. | Segment | Meaning | Detail | | :--- | :--- | :--- | | **HV** | Series Code | High Voltage or High Reliability (Standard Vertical Chip) | | **6V** | Voltage Rating | 6.3 Volts | | **331** | Capacitance Code | 33 followed by 1 zero = **330µF** | | **M** | Tolerance | ±20% (Industry Standard) | | **F80** | Case Size Code | Refers to Diameter x Length (e.g., 6.3 x 7.7mm) | | **Q-R2** | Packaging | Tape and Reel (TR) specifications | --- ### 3. Key Technical Characteristics * **Polarity:** As an electrolytic capacitor, this is a **polarized** component. The negative terminal is usually marked with a black or colored stripe on the top of the "can." * **ESR (Equivalent Series Resistance):** This series generally offers low ESR to handle ripple current effectively without overheating. * **Reflow Soldering:** Designed to withstand the high temperatures of lead-free reflow soldering processes. ### 4. Common Applications Due to its 6.3V rating and 330µF capacity, this part is commonly used for: * **Voltage Smoothing:** Cleaning up noise in 3.3V or 5V power rails. * **Decoupling:** Providing a local energy reservoir for integrated circuits (ICs). * **Consumer Electronics:** Used in laptops, motherboards, and peripheral devices where height (low profile) is a constraint. ---
