The part number **RVR-10V151MF61U-R2** identifies a high-quality Surface Mount (SMD) Aluminum Electrolytic Capacitor, typically manufactured by ELNA (or part of their RVR series). These components are designed for high-density electronic circuits requiring long-term reliability and low impedance. --- ### 1. Technical Specifications Below is a breakdown of the core electrical and physical parameters: | Parameter | Value / Specification | | :--- | :--- | | **Capacitance** | 150 µF | | **Rated Voltage** | 10 VDC | | **Tolerance** | ±20% (M) | | **Temperature Range** | -40°C to +105°C | | **Endurance** | 2,000 to 5,000 hours (depending on specific RVR sub-series) | | **Package Type** | SMD (Chip Type) | | **Case Size (Code)** | F61 (Approx. 6.3mm diameter x 5.8mm height) | --- ### 2. Part Number Breakdown Understanding the alphanumeric code helps in identifying the specific characteristics: * **RVR**: The Series name (Low Impedance, 105°C Vertical Chip type). * **10V**: Rated Working Voltage (10 Volts). * **151**: Capacitance code. The first two digits (15) are the value, and the third (1) is the multiplier ($15 \times 10^1 = 150$ µF). * **M**: Capacitance Tolerance ($\pm 20\%$). * **F61**: Case Size code (Determines the physical diameter and height). * **U-R2**: Packaging and Lead-free/RoHS compliance markers (usually indicates Tape & Reel). --- ### 3. Key Features and Applications #### Key Features * **Low Impedance:** Specifically engineered to provide low resistance at high frequencies, making it efficient for power filtering. * **Reflow Soldering Compatible:** Designed to withstand the high temperatures of automated SMD assembly lines. * **Compact Form Factor:** The "Vertical Chip" design saves significant PCB real estate compared to through-hole radial capacitors. #### Common Applications * **Power Supplies:** Used in DC-DC converters and switching regulators for smoothing output voltage. * **Automotive Electronics:** Suitable for infotainment systems or sensor modules due to the 105°C temperature rating. * **Consumer Electronics:** Found in laptops, tablets, and gaming consoles where space is limited but high capacitance is required. --- ### 4. Handling and Soldering When using the **F61** size SMD capacitor: 1. **Polarity:** These are polarized components. Ensure the dark stripe on the top of the casing aligns with the negative (-) terminal on the PCB. 2. **Baking:** If the components have been exposed to humidity for a long period, "pre-baking" may be required to prevent the "popcorn effect" during reflow. 3. **Shelf Life:** Electrolytic capacitors can dry out over many years; always check the manufacturing date code for long-term storage parts.
