The **M3V16V1CJ-R** is a specific part number for a Surface Mount (SMD) **Aluminum Electrolytic Capacitor**, typically manufactured by **Elna** or similar electronic component manufacturers focusing on high-reliability miniature components. --- ## 1. Technical Specifications Below is the technical breakdown of the component based on the standard naming convention for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Capacitance** | 100 µF (Typical for '101' or '1CJ' coding variants) | | **Voltage Rating** | 16V DC | | **Tolerance** | ±20% | | **Operating Temperature** | -40°C to +105°C | | **Series** | RV2 (or equivalent high-temp series) | | **Packaging** | Tape & Reel (indicated by -R) | --- ## 2. Key Features ### Miniature "V-Chip" Design The "V" in the part number usually refers to the vertical chip construction. These are designed for automated pick-and-place assembly on printed circuit boards (PCBs). ### Temperature Resilience Rated for **105°C**, this part is more robust than standard 85°C capacitors, making it suitable for automotive or industrial applications where heat dissipation is a concern. ### Polarity As an electrolytic capacitor, this part is **polarized**. The top of the cylindrical can usually features a black or colored marking to indicate the negative (-) terminal. --- ## 3. Common Applications These parts are commonly found in the following electronic circuits: * **Power Filtering:** Smoothing out ripples in DC-DC converters. * **Bypassing:** Providing a local energy reservoir for integrated circuits. * **Decoupling:** Reducing noise between different stages of an electronic system. * **Consumer Electronics:** Used in laptops, monitors, and power adapters due to the small footprint. --- ## 4. Marking Identification If you are looking at the physical part, you will likely see: * **A line or bar:** Indicating the negative cathode. * **16V:** The maximum working voltage. * **Date Code:** Usually a letter and number representing the manufacturing year and week.
