The part number **HT-10V471MH10EX-R2** refers to a specific **Aluminum Electrolytic Capacitor**. These components are essential in electronics for energy storage, filtering, and smoothing power supplies. Below is a detailed breakdown of its electronic specifications and characteristics based on the standard naming conventions for these series. ### 1. Key Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Type** | Aluminum Electrolytic | Uses an electrolyte liquid/gel to achieve high capacitance. | | **Capacitance** | 470 $\mu$F | Indicated by "471" (47 x 10^1). | | **Voltage Rating** | 10V | The maximum DC voltage it can continuously handle. | | **Tolerance** | ±20% (M) | Standard tolerance for electrolytic capacitors. | | **Size Code** | H10 | Typically refers to the physical dimensions (e.g., 8x10mm). | | **Mounting Type** | SMD / V-Chip | Designed for Surface Mount Technology (SMT). | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying replacement parts: 1. **HT**: Series prefix. This often denotes a **High Temperature** or low-impedance series capable of operating up to **105°C**. 2. **10V**: The Rated Working Voltage (WVDC). 3. **471**: Capacitance value in Picofarads (pF). The first two digits are the significant figures, and the third is the multiplier ($47 \times 10^1 = 470 \mu F$). 4. **M**: Capacitance tolerance code (M = ±20%). 5. **H10**: Case size identifier. 6. **EX-R2**: Packaging and environmental compliance suffix (usually denotes RoHs compliance and Tape & Reel packaging). --- ### 3. Electronic Functions and Applications Capacitors with these specific ratings (Low voltage, mid-range capacitance) are commonly used for: * **Power Decoupling:** Placed near ICs to stabilize voltage and suppress noise. * **DC-DC Converters:** Acts as an output filter to smooth out voltage ripples. * **Audio Circuits:** Used for AC coupling or DC blocking in low-voltage audio signals. * **Space-Constrained Devices:** Because it is an SMD (V-Chip) component, it is ideal for compact PCB designs like laptops, motherboards, and IoT devices. --- ### 4. Circuit Symbol and Polarity Aluminum electrolytic capacitors are **polarized**. * **Marking:** The top of the component usually has a black or colored "half-moon" or bar marking indicating the **Negative (-)** terminal. * **Schematic Symbol:** ```text +| |- ----| |---- | | ``` ---
