The **HT-16V151MF80EQ-R2** is a surface-mount (SMD) **Aluminum Electrolytic Capacitor**. These components are widely used in power management for filtering, smoothing, and buffering applications. ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Capacitance** | 150 µF | | **Voltage Rating** | 16 V DC | | **Tolerance** | ±20% | | **Operating Temp** | -55°C to +105°C | | **Package/Case** | SMD (V-Chip) | | **Series** | HT (High Temperature / Low Impedance) | | **Dimensions** | Approx. 6.3mm x 7.7mm (Typical for MF80 size code) | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific coding convention used by manufacturers like **Lelon** or similar electrolytic capacitor producers: * **HT**: Series designation (often indicating High Temperature or Low Impedance). * **16V**: The rated working voltage (16 Volts). * **151**: The capacitance value. The first two digits are significant figures, and the third is the multiplier (15 + one zero = 150µF). * **MF80**: Size code. This refers to the physical dimensions of the cylindrical can (Diameter x Height). * **EQ**: Packaging or specific material code (e.g., Lead-free, RoHS compliant). * **R2**: Taping and Reeling specification for automated assembly. --- ### 3. Key Electronic Characteristics * **Low ESR (Equivalent Series Resistance):** The HT series is designed to handle high ripple currents and provide low resistance to high-frequency signals. * **Polarity:** This is a polarized component. It must be installed in the correct orientation (+/-) to avoid failure or explosion. * **Long Life:** Rated for high-temperature durability (usually 2,000 to 5,000 hours at 105°C). --- ### 4. Common Applications Due to its 16V rating and 150µF capacity, this part is commonly found in: 1. **DC-DC Converters:** Smoothing output voltage in power supplies. 2. **Motherboards/Graphic Cards:** Decoupling noise from high-speed processors. 3. **Consumer Electronics:** Power regulation in LED drivers and chargers. 4. **Automotive Infotainment:** Operating in environments with temperature fluctuations. ---
