Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Capacitance** | 1000 µF (standard value) | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% | | **Operating Temperature** | -55°C to +125°C | | **Endurance** | Up to 4,000 hours @ 125°C | | **ESR (Equivalent Series Resistance)** | Extremely Low (typically 20mΩ range) | | **Form Factor** | SMD (Surface Mount Device) | --- ### 2. Core Technologies This specific part belongs to the "Hybrid" category, which uses a unique internal construction: * **Liquid Electrolyte:** Provides the "self-healing" mechanism for the dielectric layer, ensuring high reliability and stability over time. * **Solid Polymer:** Provides high conductivity, which significantly reduces the ESR (Internal resistance) and allows the part to handle much higher ripple currents compared to standard aluminum capacitors. --- ### 3. Advantages & Applications #### Advantages: * **Thermal Stability:** Maintains capacitance even at extremely low temperatures where standard capacitors might fail. * **High Ripple Current:** Capable of handling significant AC components in power circuits without overheating. * **Compact Size:** The hybrid technology allows for a smaller footprint relative to the high capacitance and voltage rating. #### Common Applications: 1. **Automotive ECU:** Power filtering for Engine Control Units and ADAS sensors. 2. **DC/DC Converters:** Smoothing output voltage in high-frequency switching power supplies. 3. **LED Lighting:** Ensuring flicker-free power delivery in high-wattage drivers. 4. **Telecommunications:** Base station power modules requiring long-term reliability. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer (often associated with brands like **Eaton** or **CapXon**), the code usually breaks down as follows: * **ECST:** Series identifier (Polymer Hybrid Aluminum). * **1V:** Voltage code (typically 35V). * **102:** Capacitance code (10 + 2 zeros = 1000µF). * **1020:** Physical dimensions (e.g., 10mm diameter x 20mm height). * **R:** Packaging suffix (usually Tape & Reel). ---
