The **HT-16V271MG10-R2** is a specific part number for an **Aluminum Electrolytic Capacitor**, typically categorized under Surface Mount Device (SMD) components. These parts are commonly used in power management circuits for filtering, decoupling, and energy storage. Below is a detailed breakdown of the technical specifications and characteristics associated with this part number. --- ## 1. Technical Specifications Based on the standard nomenclature for this series, here are the primary electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor (SMD Type) | | **Capacitance** | 270 µF (indicated by "271") | | **Voltage Rating** | 16V (indicated by "16V") | | **Tolerance** | ±20% (Standard for electrolytic caps) | | **Temperature Range** | -55°C to +105°C (Standard "V" or "H" series) | | **Package/Case** | V-Chip (Surface Mount) | | **Size Code** | G10 (typically refers to 10mm diameter) | --- ## 2. Part Number Breakdown Understanding the alphanumeric string helps in identifying the physical and electrical limits of the device: * **HT**: Often refers to a High-Temperature series or the specific Manufacturer prefix (common in brands like Lelon or Samxon). * **16V**: The maximum working voltage (DC). Operating above this will lead to component failure. * **271**: The capacitance value in picofarads (pF) using the three-digit code: `27` followed by `1` zero = 270,000,000 pF = **270 µF**. * **MG10**: Size and Series code. "G10" usually denotes a case size of approximately **10mm x 10.2mm**. * **R2**: Packaging suffix, usually indicating **Tape & Reel** (standard for automated SMT assembly). --- ## 3. Key Features & Applications ### Key Features * **Low Impedance**: Designed to handle high-frequency ripple currents effectively. * **SMD Design**: Flat bottom (V-chip) for automated pick-and-place machine compatibility. * **Polarized**: Must be installed with the correct orientation (indicated by a black mark on the top of the cylinder). ### Common Applications 1. **DC-DC Converters**: Smoothing out voltage ripples in power supplies. 2. **Motherboards/Graphics Cards**: Localized voltage regulation for processors. 3. **Consumer Electronics**: Used in chargers, LED drivers, and audio equipment. 4. **Telecommunications**: Filtering noise on power lines. --- ## 4. Handling and Soldering Since this is an SMD Aluminum Electrolytic capacitor, specific care must be taken during the PCBA (Printed Circuit Board Assembly) process: ```markdown - Reflow Soldering: Must follow the specific JEDEC profile to avoid "bulging" the safety vent. - Polarity: The negative terminal is marked with a colored stripe (usually black or dark blue) on the top of the case. - Storage: Sensitive to moisture; should be kept in original sealed packaging until use. ```
