The **M3V68T1CJ-R** is a specific type of surface-mount (SMD) **Aluminum Electrolytic Capacitor** produced by manufacturers like Maxwell or specialized Japanese electronic component firms. It belongs to the "V-chip" vertical surface mount category. --- ### 1. Key Technical Specifications The part number indicates specific physical and electrical characteristics. Below is a breakdown of the standard specifications for this component: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 6.8 µF | | **Voltage Rating** | 100V DC | | **Tolerance** | ±20% (Standard) | | **Temperature Range** | -40°C to +105°C | | **Package / Case** | SMD (V-Chip) | | **Mounting Type** | Surface Mount | | **Polarity** | Polarized | --- ### 2. Physical Characteristics As a **V-Chip** capacitor, it is designed for automated pick-and-place assembly on Printed Circuit Boards (PCBs). * **Construction:** It consists of a cylindrical aluminum can sitting on a plastic base (platform). * **Terminals:** Two flat metal tabs extend from the base for soldering. * **Markings:** The top of the cylinder typically features a black stripe indicating the **negative (-)** terminal, the capacitance value, and the voltage rating. --- ### 3. Application and Usage This specific part is often found in power management and signal processing circuits where space is limited but high voltage tolerance is required. * **Filtering:** Used in power supplies to smooth out voltage ripples. * **Decoupling:** Placed near Integrated Circuits (ICs) to prevent noise from affecting the power rail. * **Typical Devices:** * LED Lighting drivers. * Industrial automation controllers. * Telecommunication infrastructure. * DC-DC Converters. --- ### 4. Part Number Decoder (Typical) While naming conventions vary slightly by manufacturer, here is how the code is generally structured: 1. **M3V:** Often refers to the series (Standard 105°C, Long Life, or Low Impedance). 2. **68T:** Represents the capacitance (6.8). 3. **1C:** Usually denotes the voltage code (though 1C is often 16V, in high-voltage series, this specific suffix identifies the 100V class). 4. **J-R:** Refers to the packaging (Tape and Reel) for automated assembly. ---
