The **HTY-25V331MH10N-R2** is a surface-mount (SMD) Aluminum Electrolytic Capacitor. This specific part is commonly used in power management circuits due to its balance of capacitance and voltage rating. --- ### 1. Technical Specifications Below are the primary technical parameters for this component: | Feature | Specification | | :--- | :--- | | **Capacitance** | 330 µF (Microfarads) | | **Voltage Rating** | 25V DC | | **Tolerance** | ±20% | | **Temperature Range** | -55°C to +105°C | | **Endurance** | 2,000 to 5,000 hours (Load life at 105°C) | | **Mounting Type** | Surface Mount (SMD/V-Chip) | | **Case Size** | Approx. 8mm x 10mm (Diameter x Length) | --- ### 2. Component Breakdown The part number can be decoded to understand its construction: * **HTY:** Represents the series name. This series is typically designed for high reliability and low impedance. * **25V:** The maximum working voltage. Operating above this may cause dielectric breakdown. * **331:** The capacitance code. The first two digits (33) are the base value, and the third (1) is the multiplier ($10^1$), resulting in 330µF. * **MH10:** Refers to the physical dimensions of the "can" (Case size code). * **R2:** Usually denotes the packaging format (e.g., Tape and Reel for automated pick-and-place machines). --- ### 3. Key Characteristics and Applications * **Polarity:** As an electrolytic capacitor, this is a **polarized** component. It must be installed correctly (Positive/Negative) to avoid failure or explosion. * **Low ESR:** These are often designed with low Equivalent Series Resistance, making them efficient at filtering high-frequency noise. * **Typical Uses:** * **DC-DC Converters:** Smoothing output voltage. * **Power Supplies:** Filtering ripple current in consumer electronics. * **Automotive/Industrial:** Used in modules requiring stability under temperature fluctuations. --- ### 4.
