The **MVH66V2CD-R** is a specific part number associated with high-frequency, surface-mount (SMD) aluminum electrolytic capacitors, typically manufactured by **United Chemi-Con (Nippon Chemi-Con)**. These components are part of the **MVH series**, which is designed for high-temperature reliability and low impedance. --- ### 1. Technical Specifications Breakdown The part number follows a specific nomenclature that defines its electrical and physical properties. | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | MVH | High temperature, low impedance, vertical chip type. | | **Voltage Rating** | 6.6V - 50V (Typical) | The "66" usually denotes a specific voltage or internal code. | | **Capacitance** | Variable | Usually ranges from 47µF to 4700µF depending on case size. | | **Operating Temp** | -40°C to +125°C | Designed for harsh automotive or industrial environments. | | **Endurance** | 1,000 to 5,000 hours | Rated life at maximum operating temperature. | | **Mounting Type** | SMD / SMT | Surface mount "V-chip" design. | --- ### 2. Key Features The MVH series is engineered for high-performance electronic circuits that require stability under thermal stress. * **Low ESR/Impedance:** Designed to handle high ripple currents and provide stable power filtering at high frequencies. * **AEC-Q200 Qualified:** Most parts in this series meet automotive reliability standards, making them vibration-resistant. * **Reflow Soldering Compatible:** Specifically designed to withstand the heat of lead-free SMT reflow profiles. * **Compact Form Factor:** The "Vertical" (V-chip) construction saves PCB real estate compared to radial leaded capacitors. --- ### 3. Common Applications These capacitors are found in electronic control units where heat and power efficiency are critical: 1. **Automotive Electronics:** Engine Control Units (ECUs), ADAS modules, and LED lighting drivers. 2. **Industrial Power Supplies:** DC-DC converters and switching regulators. 3. **Telecommunications:** Base station power modules and networking hardware. --- ### 4. Identification and Marking On the physical component, you will typically see: * A negative pole indicator (usually a black or colored bar on the top). * The capacitance value (e.g., `100` for 100µF). * The voltage code (e.g., `V` for 35V or `A` for 10V). * The series identifier (`MVH`).
