The part number **HTX-63V220MF80N-R2** refers to a high-performance **Aluminum Electrolytic Capacitor**. Based on standard industry nomenclature (common for brands like Lelon or Samyoung), here is the detailed breakdown of its electronic characteristics. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 22 uF | The charge storage capacity (220 refers to $22 \times 10^0$). | | **Voltage Rating** | 63V | Maximum DC working voltage. | | **Series** | HTX | Usually denotes High Temperature / Low ESR / Long Life. | | **Tolerance** | ±20% (M) | Standard industry capacitance tolerance. | | **Case Size** | $6.3 \times 8.0$ mm | Diameter (6.3mm) and Height (8.0mm). | | **Mounting Type** | SMD (V-Chip) | Surface Mount Device for automated PCB assembly. | --- ### 2. Breakdown of Part Number Nomenclature The part number can be decoded into specific segments: * **HTX**: The series code. These are typically designed for high reliability and are often rated for **125°C** or higher, making them suitable for automotive or industrial power supplies. * **63V**: The rated voltage (63 Volts). * **220**: The capacitance value. In capacitor coding, "220" indicates 22 microfarads ($\mu F$). * **M**: Tolerance code ($M = \pm 20\%$). * **F80**: Size code. Typically corresponds to the physical dimensions ($6.3 \text{mm} \times 8.0 \text{mm}$). * **N-R2**: Packaging and Lead-free compliance code (Tape & Reel). --- ### 3. Key Electronic Functions 1. **Filtering**: Used in DC-DC converters to smooth out voltage ripples. 2. **Decoupling**: Provides a local energy reservoir to prevent voltage drops during high-speed switching. 3. **High Temperature Resilience**: Because it belongs to the HTX series, it is designed to maintain its electrolyte integrity even in harsh thermal environments (up to 125°C - 150°C). 4. **Low ESR**: Designed with low Equivalent Series Resistance to minimize heat generation during operation. --- ### 4. Typical Applications * **Automotive Electronics**: Engine Control Units (ECUs) and infotainment systems. * **Industrial Power Supplies**: LED drivers and switching regulators. * **Telecommunications**: Base station power modules. ---
