The part number **HT-16V151MF80-R2** refers to a high-temperature, surface-mount (SMD) aluminum electrolytic capacitor. This component is designed for power management and filtering in electronic circuits where space and thermal resistance are critical. --- ### 1. Part Number Specification Breakout While naming conventions vary slightly by manufacturer (such as Lelon or CapXon), the alphanumeric string typically breaks down as follows: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **HT** | Series Code | High Temperature / Low Impedance series | | **16V** | Voltage Rating | 16 Volts (Maximum operating voltage) | | **151** | Capacitance | 150 µF (15 followed by one zero) | | **M** | Tolerance | ±20% (Standard for electrolytic capacitors) | | **F80** | Case Size | Often denotes 6.3mm x 7.7mm or 8mm diameter | | **R2** | Packaging | Reel / RoHS 2 Compliance | --- ### 2. Technical Characteristics This specific capacitor is built using aluminum foil and an electrolyte solution, optimized for surface mount technology (SMT). * **Capacitance:** 150 µF * **Voltage (DC):** 16V * **Operating Temperature:** Usually rated up to **105°C** or **125°C** (depending on the "HT" series specifics). * **Mounting Type:** SMD (V-Chip), allowing for automated "Pick and Place" assembly. * **Polarity:** Polarized (must be installed with correct positive/negative orientation). --- ### 3. Common Applications Due to its 16V rating and 150µF capacity, it is commonly found in: 1. **DC-DC Converters:** Smoothing output voltage ripples. 2. **Automotive Electronics:** Used in infotainment or lighting control modules due to high-temperature stability. 3. **Consumer Electronics:** Power supply filtering in laptops and telecommunications equipment. 4. **LED Drivers:** Providing stable current and filtering noise. --- ### 4. Footprint/PCB Design When designing a PCB for this part, ensure the landing pattern accounts for the **V-Chip** base plate. The "F80" designation usually implies a specific diameter and height; always verify the physical dimensions against the manufacturer's datasheet before finalizing the layout. ```yaml Component_Type: Aluminum Electrolytic Package: V-Chip (SMD) Pitch: ~2.2mm to 3.2mm (standard for 6.3-8mm cans) ```
