The part number **47DV-1012-R** generally refers to a specific series of high-performance **Aluminum Electrolytic Capacitors**, typically associated with manufacturers like *Lelon* or similar component suppliers specializing in miniature V-chip (Surface Mount) technology. Below is a detailed breakdown of the technical specifications and characteristics of this electronic part. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor (SMD Type) | | **Capacitance** | 100 $\mu$F (Typical for this series coding) | | **Voltage Rating** | 10V to 50V (Depends on specific sub-series) | | **Case Size** | $10 \times 12.5$ mm (Diameter $\times$ Length) | | **Mounting Type** | Surface Mount Device (SMD/V-Chip) | | **Tolerance** | $\pm 20\%$ at 120Hz, 20°C | | **Operating Temperature** | -40°C to +105°C | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "47DV" nomenclature usually follows this logic: * **47DV**: Refers to the series name. The "DV" series is often characterized by **low impedance** and high stability, designed for vertical surface mounting on PCBs. * **1012**: This numerical code typically denotes the physical dimensions. In this case, it indicates a diameter of **10mm** and a height/length of **12.5mm**. * **-R**: This suffix almost always signifies **RoHS Compliance** (Restriction of Hazardous Substances), meaning the part is lead-free. --- ### 3. Key Features * **Low Impedance:** Designed to handle high-frequency ripple currents, making it ideal for power filtering. * **V-Chip Design:** The flat base allows for automated pick-and-place assembly on high-density circuit boards. * **Long Life:** These capacitors are rated for endurance (often 2,000 to 5,000 hours) at their maximum rated temperature (105°C). --- ### 4. Common Applications These components are widely used in industrial and consumer electronics where space is limited but high performance is required: 1. **DC-DC Converters:** For smoothing output voltage. 2. **Motherboards & Peripherals:** Used in power management stages. 3. **LED Lighting Drivers:** To ensure stable current delivery. 4. **Telecommunications:** In networking equipment and routers. ---
