The **M3V15V1CJ-R** is a specific part number belonging to a series of **Aluminium Electrolytic Capacitors**, typically designed for surface mount (SMD) applications. These parts are often categorized under the "V-type" or similar vertical SMD series from manufacturers like Elna or Rubycon (though specific prefixes can vary by brand, the specs below follow the standard industry nomenclature for this series). --- ## 1. Technical Specifications Below are the primary electronic characteristics for the M3V15V1CJ-R: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 15 µF | | **Rated Voltage** | 16V DC | | **Tolerance** | ±20% (M) | | **Mounting Type** | Surface Mount (SMD) | | **Case Size** | Often 4mm or 5mm diameter (Standard V-Chip) | | **Operating Temp** | -40°C to +85°C (Standard) or +105°C | | **Packaging** | Tape & Reel (-R suffix) | --- ## 2. Key Components & Construction The "M3V" series typically refers to a **Low Profile** or **General Purpose** electrolytic capacitor. Its construction includes: * **Anode/Cathode:** Aluminum foil separated by an electrolyte-soaked paper. * **Case:** Cylindrical aluminum can mounted on a plastic base (chip) for SMD soldering. * **Electrolyte:** A liquid chemical that allows for high capacitance in a small volume. * **Terminals:** Two metal tabs at the bottom designed for reflow soldering. --- ## 3. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code generally breaks down as follows: 1. **M3V:** The series code (often denoting 105°C or specific impedance levels). 2. **15:** The capacitance value (15 Microfarads). 3. **V:** Indicates the voltage rating code (V often stands for 16V or 35V depending on the brand's chart). 4. **1C:** Represents the Voltage code (C is commonly 16V). 5. **J:** Tolerance or size code. 6. **-R:** Lead-free/RoHS compliant and provided on **Reel**. --- ## 4. Common Applications * **Decoupling:** Removing noise from power supply lines. * **Filtering:** Smoothing out ripple voltage in DC-DC converters. * **Bypassing:** Providing a low-impedance path for AC signals to ground. * **Consumer Electronics:** Found in laptops, monitors, and small household appliances due to its small footprint. ---
