The **M3V22V2J-R** is a specific part number typically associated with an **SMD (Surface Mount Device) Aluminum Electrolytic Capacitor**, often part of a "V" series or similar line from manufacturers like Elna, Nichicon, or generic high-precision vendors. Below is a breakdown of the electronic specifications and characteristics based on the standard coding conventions for this part number. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 22 µF | The energy storage capacity. | | **Voltage Rating** | 35V | The maximum continuous DC voltage the part can handle. | | **Mounting Type** | SMD / SMT | Surface Mount Technology (V-Chip). | | **Tolerance** | ±20% (M) | Standard industry tolerance for electrolytic capacitors. | | **Temp Range** | -40°C to +105°C | Designed for high-reliability environments. | | **Packaging** | Tape & Reel (R) | Supplied on a reel for automated pick-and-place. | --- ### 2. Part Number Breakdown The nomenclature usually follows this structure: * **M**: Typically denotes the tolerance code (M = ±20%). * **3V**: This is often a series prefix or a specific physical size code. * **22**: The base capacitance value (22). * **V**: Denotes the Voltage (V-series) or a specific voltage multiplier depending on the manufacturer. * **2J**: Specific case size and height dimensions (e.g., 5mm x 5.4mm). * **-R**: Indicates **RoHS Compliant** and **Tape & Reel** packaging. --- ### 3. Key Applications Because of its small footprint and 105°C temperature rating, this part is commonly used in: * **DC-DC Converters:** Filtering noise in power supplies. * **Automotive Electronics:** Sensors and infotainment systems. * **Telecommunications:** Signal coupling and decoupling. * **Consumer Electronics:** High-density PCBs where vertical space is limited. --- ### 4. Handling and Soldering | Category | Requirement | | :--- | :--- | | **Polarity** | Polarized (Must be installed with correct +/- orientation). | | **Soldering** | Reflow soldering compatible (see manufacturer profile for peak temp). | | **Cleaning** | Alcohol-based cleaners are generally safe; avoid ultrasonic cleaning if possible. | ---
