The **HTX-25V331MH10XN-R2** is a specific part number for a high-performance **Aluminum Electrolytic Capacitor**, typically manufactured by brands like **Jianghai** or similar specialized suppliers focusing on high-reliability components. --- ### 1. Technical Specifications Below is a breakdown of the core electronic characteristics based on the standard nomenclature for this series: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 330 µF (Microfarads) | | **Rated Voltage** | 25V DC | | **Tolerance** | ±20% (M) | | **Temperature Range** | -55°C to +125°C (High Temp Series) | | **Dimensions** | 10mm (Diameter) x 12.5mm or 16mm (Length) | | **Mounting Type** | Through-Hole (Radial Lead) | | **Life Span** | Typically 2,000 to 5,000 hours at 125°C | --- ### 2. Part Number Breakdown Understanding the suffix and prefix codes helps in identifying the specific physical and chemical build: * **HTX**: Represents the specific series (usually Low ESR, High Temperature, High Ripple Current). * **25V**: The maximum working voltage. * **331**: The capacitance code. `33` followed by `1` zero = 330µF. * **M**: Tolerance code (±20%). * **H**: Usually denotes the height/case size code. * **10XN**: Refers to the diameter (10mm) and lead spacing/packaging. * **R2**: Lead processing code (e.g., cut leads or specific taping for automated insertion). --- ### 3. Key Electronic Features * **Low ESR (Equivalent Series Resistance):** Designed to handle high-frequency switching and minimize heat generation. * **High Ripple Current:** Capable of handling significant AC components on top of the DC voltage, which is essential for power supplies. * **Thermal Stability:** Rated for **125°C**, which is higher than standard 85°C or 105°C capacitors, making it suitable for automotive or industrial environments. --- ### 4. Common Applications Due to its temperature rating and low impedance, this part is commonly found in: 1. **Automotive Electronics:** Engine control units (ECUs) and sensor modules. 2. **LED Drivers:** Where heat buildup is significant. 3. **DC-DC Converters:** Filtering noise in compact power supplies. 4. **Industrial Telemetry:** Equipment located in harsh outdoor or factory environments.
