Below is a detailed breakdown of its electronic characteristics and specifications. ### 1. Part Number Breakdown While naming conventions can vary slightly between manufacturers, this part number typically decomposes as follows: | Code Segment | Description | Specific Value | | :--- | :--- | :--- | | **HT** | Series Name | High Temperature / Standard SMD | | **10V** | Rated Voltage | 10 Volts DC | | **331** | Capacitance Code | 330 µF (33 + one 0) | | **M** | Tolerance | ±20% | | **G10** | Case Size Code | Typically 8.0 x 10.0 mm | | **N** | Internal Code | Standard Lead-free/RoHS | | **R2** | Packaging | Tape & Reel (13" or 15" reel) | --- ### 2. Technical Specifications These capacitors are designed for general-purpose filtering, decoupling, and bypass applications in electronic circuits. * **Capacitance:** 330 Microfarads (µF). This is the amount of electrical charge the component can store. * **Rated Voltage:** 10V DC. This is the maximum continuous voltage the capacitor can handle without failure. * **Tolerance:** ±20%. The actual capacitance may vary between 264 µF and 396 µF. * **Operating Temperature:** Usually rated for **-40°C to +105°C**. * **Load Life:** Typically rated for 2,000 hours at its maximum rated temperature (105°C). --- ### 3. Physical & Mechanical Characteristics The "G10" suffix indicates a standard V-Chip (Vertical Chip) SMD form factor. | Feature | Specification | | :--- | :--- | | **Mounting Type** | Surface Mount (SMD) | | **Shape** | Cylindrical (V-Chip) | | **Dimensions** | ~8mm Diameter x 10mm Height | | **Material** | Aluminum Electrolytic (Polarized) | --- ### 4. Key Applications * **Power Supplies:** Used for smoothing output voltage in DC-DC converters. * **Audio/Video:** Decoupling signals and preventing noise. * **Automotive/Industrial:** General-purpose filtering in modules where space is limited but high capacitance is required. --- ### 5. Circuit Design Notes 1. **Polarity:** As an electrolytic capacitor, it is **polarized**. The negative terminal is usually marked with a dark stripe on the top of the casing. 2. **Voltage Derating:** It is recommended to use the capacitor at a working voltage lower than the 10V rating (e.g., in a 5V or 3.3V circuit) to ensure long-term reliability. 3. **Reflow Soldering:** Ensure the soldering profile matches the "HT" (High Temperature) series requirements to avoid bulging or drying out the electrolyte during assembly.
