The **UPV0J331MFD** is a specific aluminum electrolytic capacitor manufactured by **Nichicon**. It belongs to the **PV series**, which is characterized by a long life and high reliability. --- ### Technical Specifications | Parameter | Value / Detail | | :--- | :--- | | **Manufacturer** | Nichicon | | **Series** | PV (Long Life) | | **Capacitance** | 330 µF | | **Voltage Rating** | 6.3 VDC | | **Tolerance** | ±20% | | **Temperature Range** | -55°C to +105°C | | **Lifetime** | 5,000 hours @ 105°C | | **Mounting Type** | Through-Hole (Radial Lead) | | **Dimensions** | 8.00mm Diameter x 11.50mm Length | | **Lead Spacing** | 3.50mm | --- ### Key Features and Construction 1. **Electrolytic Dielectric:** It uses an electrolyte solution to achieve high capacitance in a small volume. It is a **polarized** component, meaning it must be installed with the correct orientation (positive and negative). 2. **Long Life Series:** The "PV" designation indicates it is designed for longevity. While standard capacitors might be rated for 1,000 or 2,000 hours, this unit is rated for **5,000 hours** at its maximum operating temperature. 3. **Low ESR/High Reliability:** These parts are typically designed to handle ripple currents effectively while maintaining stability over time. ### Part Number Breakdown The alphanumeric code provides specific information about the component's build: * **UPV**: Series Code (Long Life, 105°C). * **0J**: Voltage Rating (0J = 6.3 Volts). * **331**: Capacitance Code ($33 \times 10^1 = 330$ picofarads in standard notation, but represented as 330µF for these units). * **MFD**: Packaging/Lead Type (Usually indicates bulk packaging with standard radial leads). ### Typical Applications * **Power Supplies:** Filtering high-frequency noise in low-voltage DC lines. * **Motherboards:** Local decoupling for integrated circuits. * **Industrial Equipment:** Used where maintenance is difficult and long component life is required. * **Consumer Electronics:** General-purpose smoothing and buffering. ---
