These components are used primarily for energy storage, filtering, and smoothing in power supplies and audio circuits. ### 1. Part Number Breakdown The alphanumeric string contains the technical specifications defined by the manufacturer (likely *Samyoung* or a similar Korean manufacturer): | Segment | Meaning | Specification | | :--- | :--- | :--- | | **HT** | Series Code | High temperature / Standard reliability series | | **16V** | Voltage Rating | 16 Volts (Maximum operating voltage) | | **471** | Capacitance | 470 µF (Microfarads) | | **M** | Tolerance | ±20% | | **H10** | Case Size | Often 8mm x 11.5mm or 10mm height | | **EXN** | Internal Code | Lead type or electrolyte formulation | | **R2** | Packaging | Reel or specific lead spacing/taping | --- ### 2. Key Technical Specifications Based on standard industry conventions for this specific series: * **Capacitance:** 470 µF. This is a medium-range value, typically used for decoupling power rails in consumer electronics. * **Voltage:** 16V DC. This indicates the capacitor is safe for use in circuits up to 12V (providing a safety margin). * **Type:** Radial Lead (through-hole). This part has two wires coming out of the bottom for PCB mounting. * **Polarity:** Polarized. One lead is positive and the other is negative (usually marked with a stripe on the body). * **Temperature Range:** Usually rated up to **105°C**, which is higher than the standard 85°C, offering better longevity. --- ### 3. Applications and Usage This specific capacitor is commonly found in: 1. **Switching Power Supplies:** Used to smooth output ripple voltage. 2. **Motherboards/PCBs:** To stabilize voltage near Integrated Circuits (ICs). 3. **Audio Equipment:** Used in signal coupling or power filtering to reduce hum. 4. **LED Drivers:** To provide constant current flow by buffering the DC output. ### 4.
