The **M3V68V1CJ-R** is a specific part number for a **Surface Mount (SMD) Aluminum Electrolytic Capacitor**, typically manufactured by companies like **Elna** or **Nichicon** (depending on the specific series prefix). These components are designed for high-reliability applications where space is limited and vertical mounting is required. --- ### 1. Component Specifications Based on the standard nomenclature for this part series, here are the primary technical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor (V-Chip) | | **Capacitance** | 68 µF | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% (Standard) | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temp** | -40°C to +105°C (Standard for "V" series) | | **Packaging** | Tape & Reel ("-R" suffix) | --- ### 2. Breakdown of Part Number Syntax While manufacturers vary slightly, the code generally breaks down as follows: * **M3 / MV:** Often designates the series (e.g., standard vertical chip). * **68:** The nominal capacitance in microfarads (68µF). * **V:** Usually indicates the working voltage (35V in many coding systems, or simply "Vertical" orientation). * **1CJ:** A combination code for dielectric type, case size, and specific tolerance ratings. * **-R:** Indicates that the parts are supplied on a **Reel** for automated pick-and-place assembly. --- ### 3. Key Physical Features * **Case Shape:** Often referred to as a "V-Chip" because of its cylindrical body sitting on a square plastic base (the "seat"). * **Reflow Soldering:** Designed to withstand the heat of infrared or convection reflow ovens. * **Polarity:** Like all electrolytic capacitors, it is **polarized**. The negative terminal is usually marked with a black stripe on the top of the aluminum can. --- ### 4. Common Applications These capacitors are used in various electronic circuits for: 1. **Power Filtering:** Smoothing out ripples in DC power supplies. 2. **Decoupling:** Providing a local energy reservoir for integrated circuits. 3. **Bypassing:** Diverting AC noise to the ground in signal processing. 4. **Consumer Electronics:** Found in motherboards, automotive modules, and telecommunications equipment. ---
