The part number **HT-35V271MH10EQ-R2** refers to a specific **Aluminum Electrolytic Capacitor**. These components are widely used in electronic circuits for power filtering, energy storage, and noise decoupling. Below is the technical breakdown of the specifications based on standard nomenclature for these types of surface-mount (SMT/SMD) components. --- ## 1. Technical Specifications | Parameter | Value / Description | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Capacitance** | 270 µF (Microfarads) | | **Voltage Rating** | 35V DC | | **Mounting Type** | SMD (Surface Mount Device) / V-Chip | | **Series** | HT Series (High Temperature / Low Impedance) | | **Tolerance** | ±20% (Standard) | | **Case Size** | Approx. 8mm - 10mm Diameter (indicated by "H10") | --- ## 2. Key Features and Meaning of the Part Number The alphanumeric code can be decoded as follows: * **HT**: Represents the **Series**. "HT" typically indicates a high-temperature range (often up to 105°C) and low ESR (Equivalent Series Resistance). * **35V**: The **Rated Voltage**. This is the maximum continuous voltage the capacitor can withstand. * **271**: The **Capacitance Code**. The first two digits (27) are the value, and the third (1) is the multiplier ($10^1$). So, $27 \times 10 = 270$ µF. * **M**: The **Tolerance**. "M" stands for ±20%. * **H10**: Refers to the **Physical Dimensions**. This usually indicates a diameter and height profile (e.g., $10 \times 10.2$ mm or similar). * **EQ**: A factory code for internal packaging or specific electrolyte formulation. * **R2**: Usually denotes **Tape & Reel packaging** specifications for automated pick-and-place assembly. --- ## 3. Applications Due to its 35V rating and 270µF capacity, this part is commonly found in: 1. **DC-DC Converters:** Filtering input/output ripples. 2. **Power Supplies:** Providing bulk capacitance for voltage stability. 3. **Automotive Electronics:** Used in infotainment or lighting control modules where high-temperature durability is required. 4. **Industrial Controls:** Ensuring clean power delivery to microcontrollers. --- ## 4. Design Considerations * **Polarity:** As an electrolytic capacitor, it is polarized. Connecting it in reverse will cause permanent damage or explosion. * **Temperature:** Ensure the operating environment does not exceed the 105°C limit to prevent the electrolyte from drying out prematurely. * **ESR:** The HT series is optimized for low impedance, making it efficient for high-frequency switching applications.
