The **HT-16V471MH10E-R2** is a specific part number for an aluminum electrolytic capacitor. Below is a detailed breakdown of its technical specifications and characteristics. ### 1. General Specifications Based on the standard nomenclature for electronic components, here are the core parameters: | Parameter | Value | Description | | :--- | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | Polarized energy storage component. | | **Capacitance** | 470 µF | Indicated by "471" (47 x 10^1). | | **Voltage Rating** | 16V | Maximum operating DC voltage. | | **Series** | HT Series | Often denotes "High Temperature" or specific low impedance characteristics. | | **Tolerance** | ±20% (M) | Standard tolerance for electrolytic capacitors. | | **Mounting Type** | Through-Hole | Radial lead configuration. | --- ### 2. Part Number Breakdown The alphanumeric code follows a specific logic used by manufacturers (such as Samxon or similar electrolytic brands): * **HT**: The Series name (usually High Temperature/Long Life). * **16V**: The rated working voltage (16 Volts DC). * **471**: Capacitance in Picofarads (pF). $47 \times 10^1 = 470,000,000$ pF, which equals **470 µF**. * **M**: Capacitance Tolerance (M = ±20%). * **H10**: Physical Dimensions (typically refers to a diameter of 8mm or 10mm and a specific height). * **E-R2**: Packaging or Lead forming code (e.g., Bulk or Taped, RoHS 2 compliant). --- ### 3. Key Performance Characteristics Aluminum electrolytic capacitors like this one are designed for specific roles in a circuit: #### A. Temperature Rating Components in the "HT" series are typically rated for **105°C**. This makes them suitable for industrial applications or power supplies where internal heat is generated. #### B. Equivalent Series Resistance (ESR) These capacitors are often optimized for low ESR to handle ripple current effectively without overheating. #### C. Polarity As an electrolytic capacitor, it is **polarized**. One lead (usually the shorter one) is the negative (-) terminal and must be connected correctly to avoid component failure or explosion. --- ### 4. Common Applications Due to its 470µF capacitance and 16V rating, this part is commonly found in: * **Power Supply Filtering:** Smoothing DC output in 5V, 9V, or 12V rails. * **Decoupling:** Providing local energy storage for ICs to prevent voltage drops. * **Audio Equipment:** Used in coupling or bypass circuits. * **Consumer Electronics:** Found in motherboards, adapters, and chargers.
