The **EEU-FC0J152S** is a high-performance aluminum electrolytic capacitor manufactured by **Panasonic**. It belongs to the **FC Series**, which is specifically designed for low impedance and high reliability in power supply applications. ### 1. Key Specifications The following table highlights the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Capacitance** | 1500 µF | | **Voltage Rating (DC)** | 6.3 V | | **Tolerance** | ±20% | | **Operating Temperature** | -55°C to +105°C | | **Endurance (Lifetime)** | 1000 to 5000 hours (at 105°C) | | **Impedance** | Low Impedance (High Frequency) | | **Mounting Type** | Through-Hole (Radial Lead) | | **Dimensions** | 10 mm (Diameter) x 15 mm (Length) | --- ### 2. Functional Breakdown To understand how this part functions within an electronic circuit, consider these three core attributes: * **Low ESR/Impedance:** The "FC" series is optimized for low Equivalent Series Resistance (ESR). This means the capacitor generates less heat during operation and can handle high ripple currents, making it ideal for filtering noise in switching power supplies. * **Aqueous Electrolyte:** Panasonic uses a specific electrolyte formulation in the FC series that balances long life with stable performance across a wide temperature range. * **Polarized Nature:** As an aluminum electrolytic capacitor, it is polarized. The "S" suffix often denotes specific lead configurations (like shorter leads or specific taping), but the polarity must be strictly observed during installation to avoid component failure. --- ### 3. Common Applications The EEU-FC0J152S is typically found in the following scenarios: 1. **Output Filtering:** Used in DC-DC converters to smooth out voltage ripples. 2. **Motherboards & Peripherals:** Used on computer hardware where stable 3.3V or 5V rails are required. 3. **Consumer Electronics:** Found in LED drivers, chargers, and audio equipment where space is limited but high capacitance is needed. --- ### 4. Part Number Decoder Understanding the Panasonic naming convention helps in identifying substitutes: * **EEU**: Radial lead type aluminum electrolytic capacitor. * **FC**: Series name (Low impedance, 105°C). * **0J**: Voltage code (0J = 6.3V). * **152**: Capacitance code (15 followed by two zeros = 1500µF). * **S**: Lead style or packaging suffix.
