The part number **ECOG2DP153D** corresponds to a high-performance **Aluminum Electrolytic Capacitor**, typically manufactured by companies like **United Chemi-Con (UCC)**. This specific series is designed for high-reliability industrial applications. --- ### 1. Technical Specifications Below are the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 15,000 µF (15mF) | | **Voltage Rating** | 200 VDC | | **Tolerance** | ±20% (M) | | **Temperature Range** | -40°C to +85°C | | **Termination Style** | Screw Terminals (Bolt-on) | | **Case Size (Approx)** | Large Can (e.g., 63.5mm x 110mm) | | **Life Cycle** | ~2,000 to 5,000 hours at rated temp | --- ### 2. Breakdown of Part Number (Nomenclature) Most industrial capacitors follow a specific naming convention. While exact prefixes vary by brand, the code generally breaks down as follows: * **ECOG**: Series identifier (often denotes high ripple current, long life, or screw terminal type). * **2D**: Voltage code (2D usually represents **200 Volts**). * **P**: Case size or terminal configuration code. * **153**: Capacitance value in picofarads ($15 \times 10^3$ µF). The first two digits are the value, the third is the multiplier. * **D**: Tolerance or mounting style code. --- ### 3. Key Features * **High Ripple Current Handling:** Designed to manage large fluctuations in current without overheating, making it ideal for power conversion. * **Large Energy Storage:** With 15,000 µF at 200V, this capacitor stores a significant amount of energy ($E = \frac{1}{2}CV^2$). * **Screw Terminals:** Provides a secure, low-resistance connection capable of handling high amperage, common in heavy-duty machinery. --- ### 4. Common Applications Due to its high capacitance and voltage rating, the ECOG2DP153D is used in: 1. **Uninterruptible Power Supplies (UPS):** For energy buffering and filtering. 2. **Inverters & Motor Drives:** Used as a DC-link capacitor to smooth the voltage bus. 3. **Welding Equipment:** To provide the high-current pulse needed for arc welding. 4. **Renewable Energy:** Filtering in solar or wind power converters. ---
