The **RV2-50V100MU-R** is a specific surface-mount (SMD) Aluminum Electrolytic Capacitor typically manufactured by Elna (though other manufacturers use similar naming conventions). It is designed for general-purpose electronic circuits where space-saving and reliability are required. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Capacitance** | 10 µF (Microfarads) | | **Voltage Rating** | 50V DC | | **Tolerance** | ±20% (Standard M tolerance) | | **Temperature Range** | -40°C to +85°C | | **Form Factor** | SMD (Surface Mount Device) | | **Size Code** | Usually 5mm x 5.3mm (varies by brand) | | **Endurance** | 2,000 hours at 85°C | --- ### 2. Decoding the Part Number Breaking down the nomenclature helps in identifying the component's characteristics: * **RV2**: Series name (Standard 85°C Chip Type). * **50V**: Rated Voltage (Maximum working voltage is 50 Volts). * **100**: Capacitance Code. The first two digits are significant; the third is the multiplier (10 x 10^0 = 10µF). * **M**: Tolerance code (±20%). * **U**: Case size code or specialized packaging indicator. * **-R**: Tape and Reel packaging (RoHS compliant). --- ### 3. Key Features * **Surface Mount Design:** Optimized for automated pick-and-place assembly on PCBs. * **Polarized:** This is an electrolytic capacitor; it has a specific positive (+) and negative (-) terminal. Reversing polarity will damage the component. * **Low Profile:** Designed for vertical chip mounting to save board real estate. * **RoHS Compliant:** Manufactured without lead or other hazardous substances. --- ### 4. Common Applications This part is commonly found in a variety of electronic sectors: 1. **Consumer Electronics:** Filtering noise in power supplies for TVs and audio equipment. 2. **DC-DC Converters:** Providing smoothing for voltage regulation. 3. **Industrial Controls:** Coupling and decoupling signals in control boards. 4. **Automotive (Non-Safety):** Used in infotainment or lighting modules (provided temperature ratings are met). ---
