The **M3V16VAJ-R** is a specific part number typically associated with a **Surface Mount (SMD) Aluminum Electrolytic Capacitor**, specifically from the **M3 series**. These capacitors are designed for high-density surface mounting on printed circuit boards (PCBs). ### Technical Specifications Based on standard industry nomenclature for this series, here is the breakdown of the electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 10 µF to 47 µF (Depending on specific batch tolerance) | | **Voltage Rating** | 16V DC | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Series** | M3 (Standard, low profile) | | **Tolerance** | ±20% (Typical for electrolytic) | | **Operating Temp** | -40°C to +85°C | | **Case Size** | Usually 4mm x 5.4mm or 5mm x 5.4mm | --- ### Key Features 1. **Vertical Chip (V-Chip):** The "V" in the part number indicates a vertical chip construction, which minimizes the footprint on the board. 2. **Polarity:** As an aluminum electrolytic capacitor, it is polarized. The negative terminal is usually marked with a black stripe on the top of the metal casing. 3. **Reflow Soldering:** Designed to withstand the heat of infrared reflow soldering processes. 4. **Packaging:** The "-R" suffix indicates that the parts are supplied on a **Tape and Reel** for use with automated Pick-and-Place machinery. ### Common Applications These parts are general-purpose and used in a variety of electronics for: * **Decoupling:** Filtering out noise from power supply lines. * **Bypassing:** Providing a path for AC signals to ground. * **Consumer Electronics:** Used in TVs, audio equipment, and computer peripherals where space is at a premium. --- ### Comparison with Similar Capacitors Compared to Tantalum capacitors, these Aluminum Electrolytic SMDs are generally more cost-effective but have a higher ESR (Equivalent Series Resistance) and a shorter lifespan at maximum temperature ratings.
