The part number **HT-50V330MF80Q-R2** refers to a specific **Aluminum Electrolytic Capacitor**, typically used in power management and filtering circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Part Number Breakdown The alphanumeric code follows a standard naming convention used by manufacturers (often associated with brands like Samyoung or similar passive component specialists). | Segment | Value | Meaning | | :--- | :--- | :--- | | **HT** | Series | Indicates the series name (High Temperature/Long Life). | | **50V** | Voltage | Rated voltage is **50 Volts DC**. | | **330M** | Capacitance | **330 µF** (Microfarads). 'M' denotes ±20% tolerance. | | **F80** | Case Size | Dimensions (Diameter x Length). Typically **8mm x 11.5mm**. | | **Q** | Terminal Type | Standard Lead type (Radial). | | **R2** | Packaging | Reel or specific Lead forming/spacing code. | --- ### 2. Technical Specifications These components are designed for high-density electronic assemblies. * **Capacitance:** 330 µF * **Voltage Rating:** 50V DC (Maximum surge voltage is usually 1.15x rated voltage). * **Tolerance:** ±20% at 120Hz, 20°C. * **Operating Temperature:** Typically -40°C to +105°C. * **Life Span:** Often rated for 2,000 to 5,000 hours at maximum temperature. * **Polarity:** Polarized (Has a distinct positive and negative lead). --- ### 3. Key Electronic Functions In a circuit, this capacitor performs three primary roles: 1. **Filtering:** Smoothes out voltage fluctuations (ripple) in power supplies after rectification. 2. **Energy Storage:** Provides a local reservoir of energy to handle sudden increases in current demand. 3. **Decoupling:** Blocks DC components while allowing AC signals to pass, preventing noise from traveling between circuit stages. --- ### 4. Typical Applications Due to the **50V** rating and **330µF** capacity, this part is commonly found in: * **LED Drivers:** Used for stabilizing the output current. * **Switching Power Supplies (SMPS):** Secondary side filtering. * **Audio Amplifiers:** Power rail decoupling. * **Industrial Control Boards:** Voltage regulation for 24V or 36V systems. --- ### 5. Installation Precautions ```cpp // SAFETY NOTICE: 1. Polarity: Ensure the negative stripe on the sleeve matches the PCB marking. 2. Voltage: Do not exceed 50V to prevent electrolyte leakage or bursting. 3. Soldering: Observe maximum soldering heat time to avoid damaging the internal seal. ```
