The part number **HT-80V330MH10-R2** refers to a specific **Aluminum Electrolytic Capacitor**. These components are widely used for energy storage, filtering, and smoothing in power supply circuits. Below is a detailed breakdown of the electronic specifications and characteristics based on the standard naming conventions for this series. --- ### 1. Key Specifications Table | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Capacitor | Aluminum Electrolytic (Radial Lead) | | **Capacitance** | 330 $\mu$F | Total charge storage capacity | | **Voltage Rating** | 80V | Maximum continuous DC voltage | | **Tolerance** | ±20% (Standard) | Permissible deviation in capacitance | | **Temperature** | -40°C to +105°C | Operating temperature range | | **Mounting Type** | Through-Hole | Radial lead configuration | | **Series** | HT Series | High temperature/High reliability series | --- ### 2. Breakdown of Part Number Nomenclature * **HT**: Represents the **Series**. The "HT" series typically signifies high-temperature endurance (usually 105°C) and low impedance/low ESR (Equivalent Series Resistance) characteristics. * **80V**: The **Rated Voltage**. This is the maximum voltage the capacitor can withstand safely. It is recommended to run capacitors at ~80% of this rating for longevity. * **330M**: * **330**: The capacitance value (330 Microfarads). * **M**: The tolerance code, where 'M' stands for **±20%**. * **H10**: Refers to the **Physical Case Size**. In this nomenclature, it usually indicates a specific diameter and height (e.g., 10mm diameter). * **R2**: Packaging or Lead formation code. This often indicates a specific lead spacing (Pitch) or that the item is provided on a reel/tape for automated insertion. --- ### 3. Applications and Usage This specific part is often found in the following electronic environments: * **DC-DC Converters:** Used to smooth output voltage ripples. * **Power Supplies:** Acts as a bulk storage element to maintain steady voltage during load transitions. * **LED Drivers:** Provides filtering to prevent flickering in high-voltage lighting circuits. * **Industrial Electronics:** Due to the 105°C rating, it is suitable for equipment that generates significant internal heat. --- ### 4. Critical Considerations 1. **Polarity:** As an Aluminum Electrolytic capacitor, this part is **polarized**. Connecting it in reverse (negative to positive) can cause the component to vent, leak, or explode. 2. **Lifetime:** Electrolytic capacitors have a finite lifespan. The "HT" series is designed for higher "Load Life" (e.g., 2000 to 5000 hours at 105°C), which translates to much longer life at room temperature. 3. **ESR (Equivalent Series Resistance):** At 80V/330uF, this part is designed to handle moderate ripple currents without excessive internal heating.
