The part number **RVD-35V331MHA5UQ-R2** refers to a specific Aluminum Electrolytic Capacitor, typically manufactured by **Elna** (or similar manufacturers following the RVD series standards). This component is designed for Surface Mount Device (SMD) applications and is characterized by its high reliability and specific physical dimensions. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Capacitance** | 330 µF (Microfarads) | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% | | **Mounting Type** | Surface Mount (SMD / Chip) | | **Operating Temperature** | -55°C to +105°C | | **Life Span** | Usually 2000 hours @ 105°C | | **Series** | RVD (Low Profile / General Purpose) | --- ### 2. Breakdown of the Part Number The alphanumeric code contains specific manufacturing data: * **RVD**: The series name (Standard SMD Aluminum Electrolytic). * **35V**: The maximum working voltage (35 Volts). * **331**: The capacitance code. The first two digits are significant figures (33) and the third is the multiplier ($10^1$). Hence, $33 \times 10 = 330$ µF. * **M**: The tolerance code (M = ±20%). * **HA5U**: This section usually refers to the **Case Size** (Diameter x Length). For the RVD series, this typically corresponds to an $8 \times 10$ mm or $10 \times 10$ mm footprint depending on the specific catalog variation. * **Q-R2**: Packaging information, typically indicating "Tape & Reel" for automated pick-and-place assembly. --- ### 3. Key Electronic Characteristics * **Polarized:** As an aluminum electrolytic capacitor, it has a positive and negative terminal. Incorrect orientation during PCB assembly will lead to component failure. * **Low Profile:** The RVD series is designed for vertical chip mounting (V-chip) to save vertical space in compact electronics. * **Decoupling & Filtering:** This part is primarily used for power supply filtering, smoothing voltage ripples, and decoupling in consumer electronics or automotive modules. --- ### 4. Comparison with Similar Components ```markdown - Standard Electrolytic: Larger, through-hole, not suitable for automated SMD lines. - Tantalum Capacitors: Smaller footprint but much more expensive and sensitive to voltage spikes. - RVD Series: Balanced cost-to-performance ratio for mid-range voltage/capacitance needs. ```
