The **MVH68V1AD-R** is a specific part number for a high-performance **Aluminum Electrolytic Capacitor** from the **MVH Series**, manufactured by **United Chemi-Con (UCC)**. These are designed for surface-mount (SMT) applications requiring high reliability and heat resistance. --- ## Technical Specifications The alphanumeric code provides specific details about its electrical properties: | Parameter | Specification | | :--- | :--- | | **Series** | MVH (High Temperature, Low Impedance) | | **Capacitance** | 6.8 µF | | **Voltage Rating** | 100V DC | | **Tolerance** | ±20% (M) | | **Temperature Range** | -40°C to +125°C | | **Endurance** | 1,000 to 5,000 hours (depending on size/load) | | **Mounting Type** | Surface Mount (SMD / V-Chip) | --- ## Key Features ### 1. High Temperature Tolerance The MVH series is specifically engineered to operate at temperatures up to **125°C**. This makes it significantly more robust than standard 85°C or 105°C rated capacitors. ### 2. Low Impedance These capacitors are "Low ESR" (Equivalent Series Resistance) parts. This allows them to handle high ripple currents and maintain stability in high-frequency switching circuits. ### 3. Vibration Resistance The "-R" suffix often denotes specific packaging or structural reinforcements (Anti-Vibration base) designed to withstand mechanical stress in automotive or industrial environments. --- ## Common Applications The MVH68V1AD-R is typically found in environments where heat and space-saving are critical factors: * **Automotive Electronics:** Engine control units (ECUs), lighting systems, and sensors. * **Power Supplies:** DC-DC converters and switching regulators. * **Industrial Equipment:** High-density circuit boards requiring longevity under thermal stress. * **Telecommunications:** Base station power modules. --- ## Comparison with Standard Capacitors | Feature | Standard (General Purpose) | MVH68V1AD-R | | :--- | :--- | :--- | | **Max Temp** | 85°C - 105°C | 125°C | | **ESR** | High | Low | | **Longevity** | Low at high heat | High at high heat | | **Application** | Consumer Electronics | Automotive/Industrial |
