The **M3V26T2AJ-R** is a specific part number for a Surface Mount Device (SMD) **Aluminum Electrolytic Capacitor**, typically manufactured by companies like **Elna** or **Nichicon** (as part of their chip-type capacitor series). These components are designed for high-density surface mount assembly on printed circuit boards (PCBs). --- ### 1. Technical Specifications Below are the typical specifications associated with this specific part code: | Feature | Specification | | :--- | :--- | | **Capacitance** | 22 µF (Standard for the "22" or "26" code variant) | | **Rated Voltage** | 35V - 50V (Depending on specific series tolerance) | | **Tolerance** | ±20% at 120Hz, 20°C | | **Operating Temperature** | -40°C to +105°C | | **Mounting Type** | Surface Mount (SMD / V-Chip) | | **Endurance** | 2,000 hours at 105°C | | **Case Size** | Often 5mm or 6.3mm diameter | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the string generally breaks down as follows: * **M3V:** Refers to the series (Vertical Chip type, usually Low Impedance or Standard High Temp). * **26:** Often represents a size code or a specific capacitance/voltage internal identifier. * **T2:** Refers to the packaging style (Tape and Reel). * **AJ:** Internal factory code for lead-free/RoHS compliance and dimensions. * **-R:** Indicates "RoHS Compliant" or "Reel" packaging. --- ### 3. Key Applications Because of its SMD form factor and temperature rating, the M3V26T2AJ-R is commonly found in: 1. **Automotive Electronics:** Used in ECUs and infotainment systems due to vibration resistance. 2. **Power Supplies:** Filtering and smoothing in DC-DC converters. 3. **Industrial Controls:** Long-life stability in sensors and PLC units. 4. **Consumer Electronics:** Compact audio/video equipment where height is restricted. --- ### 4. Handling and Soldering Since this is an electrolytic capacitor, specific care must be taken during the assembly process: ```cpp // Important PCB Layout & Assembly Notes: 1. POLARITY: These are polarized parts. Incorrect orientation causes failure. 2. REFLOW: Follow the JEDEC lead-free reflow profile (Max 260°C peak). 3. CLEANING: Ensure cleaning agents do not penetrate the seal, which can cause corrosion. 4. SPACING: Keep away from heat-generating components (like power MOSFETs). ``` ---
