The part number **RVR-25V331MGA5UN-R2** corresponds to a specific type of Aluminum Electrolytic Capacitor, typically manufactured by companies like Elna or similar electronic component specialists. Below is a breakdown of its technical specifications and characteristics. --- ### 1. Part Number Deciphering Based on standard industry naming conventions for SMD electrolytic capacitors, the code breaks down as follows: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **RVR** | Series Name | Vertical Chip (SMD) Type, Low Impedance/Standard | | **25V** | Voltage Rating | 25 Volts DC (Maximum Working Voltage) | | **331** | Capacitance | 330 µF (33 + 1 zero) | | **M** | Tolerance | ±20% | | **GA5** | Case Size | Often corresponds to ~8mm x 10mm (varies by mfg) | | **UN-R2** | Packaging/Finish | Tape & Reel, RoHS Compliant, Specific Lead Finish | --- ### 2. Technical Specifications | Parameter | Value | | :--- | :--- | | **Type** | Aluminum Electrolytic (Surface Mount) | | **Capacitance** | 330 µF | | **Rated Voltage** | 25V DC | | **Operating Temperature** | -40°C to +105°C (Standard for RVR series) | | **Endurance** | Typically 2,000 hours at 105°C | | **Mounting Type** | SMD (Surface Mount Device) | | **Polarity** | Polarized (marked with a black stripe on the top) | --- ### 3. Key Applications This specific capacitor is designed for general-purpose electronic filtering and power management. Common uses include: * **DC-DC Converters:** Smoothing output ripples. * **Consumer Electronics:** Power supply circuits for TVs, monitors, and gaming consoles. * **Automotive Infotainment:** Used in non-safety critical interior electronics. * **Telecommunications:** Local power regulation on PCBs. ### 4. Footprint and Layout Considerations Since this is an SMD component, the "GA5" code defines the physical footprint. When designing a PCB, ensure the following: * **Solder Pads:** The pads must accommodate the "V-chip" style baseplate. * **Height:** Ensure the vertical clearance is at least 10.5mm. * **Polarity:** The cathode (negative) is usually indicated by a colored bar on the top of the aluminum can. ---
