The part number **HT-35V151MG10N-R2** corresponds to an **Aluminum Electrolytic Capacitor**, typically designed for surface mount (SMD) applications. These components are essential for energy storage, filtering, and decoupling in electronic circuits. --- ### 1. Technical Specifications Based on the standard nomenclature for electrolytic capacitors, here is the breakdown of the specifications: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 150 µF | The ability to store electrical charge. | | **Voltage Rating** | 35V | The maximum DC voltage the capacitor can handle. | | **Type** | Aluminum Electrolytic | Uses an electrolyte liquid/gel to achieve high capacitance. | | **Mounting Type** | SMD (V-Chip) | Designed for Surface Mount Technology (SMT) on PCBs. | | **Tolerance** | ±20% (M) | Standard industry tolerance for electrolytic capacitors. | | **Case Size** | G10 (10x10.2mm approx) | Standardized dimensions for the metal "can." | --- ### 2. Part Number Breakdown Manufacturers often use a coded system to identify parts. Here is a typical interpretation of this specific string: * **HT**: Series prefix (Often denotes High Temperature or a specific manufacturer series). * **35V**: Rated Voltage (35 Volts). * **151**: Capacitance Code. The first two digits (15) are the value, and the third (1) is the multiplier ($15 \times 10^1 = 150 \mu F$). * **M**: Tolerance code ($M = \pm 20\%$). * **G10**: Case size code (Diameter and Length). * **N-R2**: Packaging/Revision suffix (e.g., Tape & Reel). --- ### 3. Key Features & Applications #### Features * **Polarized:** This component has a positive and negative terminal. Installing it backward can cause failure or explosion. * **High Temperature Stability:** Most "HT" series are rated for **105°C**, making them suitable for industrial environments. * **Low Profile:** The SMD "V-Chip" design allows for automated assembly and space-saving on the board. #### Typical Applications 1. **Power Supply Filtering:** Smoothing out ripples in DC-DC converters. 2. **Decoupling:** Providing a local energy reservoir for integrated circuits (ICs). 3. **Bypassing:** Diverting unwanted AC signals to the ground. 4. **Consumer Electronics:** Used in LED drivers, motherboard power phases, and telecommunications gear. --- ### 4. Precautions for Use ```markdown 1. Polarity: Ensure the cathode (indicated by a black/dark stripe on the top) aligns with the PCB markings. 2. Reflow Soldering: Follow the manufacturer's thermal profile to avoid drying out the electrolyte during assembly. 3. Voltage Derating: It is best practice to run the capacitor at 80% or less of its rated voltage (28V for a 35V part) for longevity. ```
