The part number **HT-16V471MH10EX-R2** refers to an Aluminum Electrolytic Capacitor. This specific nomenclature is typical for manufacturers like **Lelon** or similar high-quality passive component producers. Below is the technical breakdown of the part number and its electronic specifications. --- ## 1. Technical Specifications | Parameter | Value | Description | | :--- | :--- | :--- | | **Capacitance** | 470 µF | The amount of charge the capacitor can store. | | **Voltage Rating** | 16 V | Maximum DC voltage the part can handle continuously. | | **Type** | Electrolytic | Polarized capacitor using an electrolyte. | | **Mounting Type** | SMD (V-Chip) | Surface Mount Device, designed for PCB mounting. | | **Case Size** | 8 x 10 mm (approx) | Physical dimensions (Diameter x Height). | | **Tolerance** | ±20% (M) | Standard industry tolerance for electrolytic caps. | | **Temperature** | -55°C to +105°C | Operating temperature range. | --- ## 2. Part Number Deciphering Breaking down the string **HT-16V471MH10EX-R2**: * **HT**: Series code. Usually denotes "High Temperature" or "Low Impedance" characteristics. * **16V**: The Rated Working Voltage (16 Volts). * **471**: Capacitance code. The first two digits (47) are the value, and the third (1) is the multiplier ($10^1$). Result: $47 \times 10 = 470 \mu F$. * **M**: Tolerance code (M = ±20%). * **H10**: Physical size code (often H = 8mm diameter, 10 = 10mm height). * **EX**: Internal manufacturing/packaging code (RoHS compliance or specific electrolyte). * **R2**: Taping/Reel code, indicating it is supplied on a 13" or 15" reel for automated pick-and-place. --- ## 3. Key Electronic Characteristics ### ESR and Ripple Current This series is typically designed for **Low ESR (Equivalent Series Resistance)**. This makes it suitable for filtering high-frequency noise in power supplies without overheating. ### Polarity As an Aluminum Electrolytic capacitor, this component is **polarized**. * **Identification:** One side of the top surface will have a dark colored (usually black) bar marking the **negative (-)** terminal. * **Risk:** Reversing the polarity or exceeding the 16V rating can lead to component failure or venting (explosion). ### Common Applications * **DC-DC Converters:** Filtering output voltage. * **Motherboards/Graphics Cards:** Providing local energy storage for high-speed ICs. * **Consumer Electronics:** General purpose decoupling in 5V or 12V rails. ---
