The **M3V68T2J-R** is a specific part number belonging to the **M3V series** of Surface Mount (SMD) Aluminum Electrolytic Capacitors, manufactured by **Rubycon**. These capacitors are designed for high-density surface mounting and are known for their vertical construction (V-chip) and reliability in automotive and industrial applications. --- ### 1. Technical Specifications Below are the primary technical characteristics typically associated with the M3V series: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Rubycon | | **Capacitor Type** | Aluminum Electrolytic (SMD Type) | | **Series** | M3V (Low Impedance / High Temperature) | | **Mounting Style** | Surface Mount (V-Chip) | | **Operating Temperature** | -40°C to +125°C | | **Rated Life** | 1,000 to 2,000 hours at 125°C | | **Compliance** | AEC-Q200 Qualified (Automotive Grade) | --- ### 2. Breakdown of the Part Number While specific codes can vary by manufacturer revisions, the alphanumeric string generally follows this logic: * **M3V:** The series name (signifies high temperature, low impedance, and AEC-Q200 compliance). * **68:** Usually represents the Capacitance value (likely 68µF). * **T2:** Often refers to the size code or the lead forming style. * **J:** Often represents the Tolerance (e.g., ±20%). * **-R:** Indicates "RoHS Compliant" and "Tape & Reel" packaging. --- ### 3. Key Features The M3V series is specialized for demanding environments: 1. **High Temperature Resistance:** Rated up to **125°C**, which is significantly higher than standard 85°C or 105°C capacitors. 2. **Low Impedance:** Optimized for high-frequency filtering and noise reduction in power supplies. 3. **Automotive Grade:** It meets the AEC-Q200 standard, making it suitable for Engine Control Units (ECUs) and ADAS systems. 4. **Reflow Compatibility:** Designed to withstand the high temperatures of lead-free soldering processes. --- ### 4. Typical Applications * **Automotive Electronics:** Power steering, lighting controllers, and infotainment systems. * **Industrial Power Supplies:** DC-DC converters and switching regulators. * **Communication Infrastructure:** Networking hardware that operates in high-heat outdoor enclosures. ---
