The part number **HT-16V151MF80E-R2** refers to a **Surface Mount (SMT) Aluminum Electrolytic Capacitor**. These components are widely used for energy storage, filtering, and decoupling in electronic circuits. Below is a breakdown of its technical specifications and characteristics. ### 1. Technical Specifications Based on standard industry nomenclature for this series, here are the primary parameters: | Parameter | Value / Description | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Capacitance** | 150 µF (Microfarads) | | **Voltage Rating** | 16V DC | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Tolerance** | ±20% (Standard for electrolytic) | | **Case Size (Diameter)** | Approximately 8.0 mm | | **Operating Temp** | -55°C to +105°C (Typical for HT series) | | **Packaging** | Tape and Reel (indicated by R2 suffix) | --- ### 2. Part Number Breakdown The alphanumeric code follows a specific logic used by manufacturers like **Lelon** or **CapXon** (common producers of this series): * **HT**: Series prefix, usually indicating "High Temperature" or specific low-impedance characteristics. * **16V**: Working voltage rating (Maximum 16 Volts DC). * **151**: Capacitance code. The first two digits (15) are significant figures, and the third (1) is the multiplier ($10^1$). $15 \times 10 = 150 \mu F$. * **MF80**: Physical dimensions and lead style (M-type casing, 8.0mm diameter). * **E**: RoHS compliance / Environmental standard. * **R2**: Packaging code, typically referring to the 13-inch or 7-inch plastic reel size for automated pick-and-place machines. --- ### 3. Key Features and Applications #### Features * **Low ESR:** Designed to handle ripple current efficiently without excessive self-heating. * **Vibration Resistance:** The SMD "V-Chip" design provides better stability on PCBs compared to radial leaded types. * **Reflow Solder Compatible:** Built to withstand the high temperatures of infrared or convection soldering ovens. #### Common Applications 1. **Power Supplies:** Used in DC-DC converters for output filtering. 2. **Consumer Electronics:** Found in TVs, monitors, and gaming consoles for voltage smoothing. 3. **Automotive/Industrial:** Used in modules requiring compact, high-capacitance components that can handle up to 105°C. --- ### 4. Precautions for Use * **Polarity:** This is a polarized component. Installing it backwards will lead to gas buildup, leakage, or explosion. The negative terminal is usually marked with a black stripe on the top of the silver can. * **Voltage Derating:** For long-term reliability, it is best practice to operate the capacitor at roughly 80% of its rated voltage (e.g., use in 12V or 5V circuits).
