The part number **HT-16V820MF61E-R2** refers to a **Conductive Polymer Aluminum Solid Electrolytic Capacitor**. These components are widely used in modern electronics for power filtering due to their superior performance compared to traditional liquid electrolytic capacitors. --- ### 1. Technical Specifications Based on the standard nomenclature for this series, here are the primary technical characteristics: | Parameter | Value | Description | | :--- | :--- | :--- | | **Capacitance** | 820 µF | The amount of charge the capacitor can store. | | **Voltage Rating** | 16 V | The maximum continuous DC voltage it can handle. | | **Type** | Polymer Solid | Uses a solid conductive polymer instead of liquid electrolyte. | | **Case Size** | Φ6.3 x 11 mm (approx) | Defined by the "F61E" code (varies by manufacturer). | | **Tolerance** | ±20% (M) | Standard industry tolerance for capacitance. | | **Mounting Type** | Radial Through-Hole | Leads extend from the bottom for PCB insertion. | --- ### 2. Key Features & Advantages Solid polymer capacitors like this one offer specific benefits over standard "wet" electrolytic capacitors: * **Low ESR (Equivalent Series Resistance):** This allows the capacitor to handle high ripple currents and reduces heat generation during high-frequency operation. * **Temperature Stability:** Unlike liquid capacitors, the capacitance remains stable even at sub-zero temperatures. * **Longevity:** They do not "dry out" over time, leading to a significantly longer operational lifespan (often rated for 2,000 to 5,000 hours at 105°C). * **Safety:** They are less likely to explode or leak because they contain no liquid. --- ### 3. Application Use Cases This specific rating (16V, 820µF) is commonly found in the following circuits: 1. **Motherboards & GPUs:** Used in the VRM (Voltage Regulator Module) sections to stabilize voltage to the CPU/GPU. 2. **Switching Power Supplies:** Filtering output noise in DC-DC converters. 3. **Telecommunications:** Used in base stations and networking gear for high-reliability power management. 4. **Audio Equipment:** Provides clean power rails for high-fidelity audio circuits. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by brand (e.g., CapXon, Lelon, or others), the code generally breaks down as follows: * **HT:** Series Name (High Temperature / Low ESR series). * **16V:** Rated Voltage (16 Volts). * **820:** Capacitance value in microfarads (µF). * **M:** Tolerance (±20%). * **F61E:** Case size and lead spacing code. * **R2:** Packaging code (e.g., Taped or specific lead cut).
