The part number **HT-35V151MG10EN-R2** refers to a **Surface Mount (SMD) Aluminum Electrolytic Capacitor**. These components are primarily used for energy storage, filtering, and decoupling in electronic circuits. Below is a detailed breakdown of the technical specifications encoded in the part number and its physical characteristics. --- ## 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | Uses an electrolyte liquid to achieve high capacitance. | | **Capacitance** | 150 µF (Microfarads) | Indicated by "151" (15 x 10^1). | | **Voltage Rating** | 35V DC | The maximum continuous voltage the part can handle. | | **Mounting Type** | SMD / SMT (V-Chip) | Designed for automated surface mount assembly. | | **Size Code** | G10 (approx. 8x10mm) | Refers to the diameter and height dimensions. | | **Tolerance** | ±20% (Standard) | The allowable variance from the nominal capacitance. | --- ## 2. Part Number Breakdown While naming conventions vary slightly by manufacturer (such as Lelon, Samxon, or similar brands), the code typically follows this logic: 1. **HT**: Series prefix (often denotes High Temperature or Low Impedance characteristics). 2. **35V**: Rated working voltage (35 Volts). 3. **151**: Capacitance value. The first two digits (15) are the base, and the third (1) is the multiplier ($15 \times 10^1 = 150$). 4. **M**: Tolerance code (M = ±20%). 5. **G10**: Case size identifier. 6. **EN**: Internal manufacturing/packaging code. 7. **R2**: Tape and Reel packaging specification for automated pick-and-place. --- ## 3. Key Applications This specific capacitor is commonly found in: * **DC-DC Converters:** Smoothing output voltage ripples. * **Power Supplies:** Filtering noise in the 12V to 24V range. * **Consumer Electronics:** Used on motherboards and peripheral cards where vertical space is limited. * **Automotive/Industrial:** If the "HT" series designates high-temperature endurance (usually 105°C). --- ## 4. Physical Characteristics * **Polarity:** Being an electrolytic capacitor, it is **polarized**. The top of the cylindrical "V-chip" usually has a black or colored marking indicating the **negative (-)** terminal. * **Form Factor:** It features a square plastic base to stabilize the component during reflow soldering. ---
