The part number **ECOS2DB561DA** refers to a high-quality aluminum electrolytic capacitor manufactured by **Panasonic**. This specific component belongs to the **TS-ED series**, which is known for its "snap-in" terminal design and high temperature durability. --- ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Panasonic | | **Capacitance** | 560 µF | | **Tolerance** | ±20% | | **Voltage Rating** | 200V DC | | **Temperature Rating** | -25°C to +105°C | | **Lifetime** | 3,000 hours at 105°C | | **Termination Style** | Snap-In (2 Pins) | | **Form Factor** | Can (Radial - Snap-In) | | **Dimensions** | Approx. 30mm (Diameter) x 30mm (Length) | --- ## Key Features ### 1. Snap-In Terminals The "Snap-In" design refers to the physical leads that are shaped to lock into a printed circuit board (PCB) before soldering. This prevents the component from falling out or shifting during the wave soldering process. ### 2. TS-ED Series Characteristics * **High Ripple Current:** Designed to handle significant fluctuations in current, which is critical for power supply stability. * **Compact Size:** Offers a high capacitance-to-volume ratio, making it suitable for dense electronic assemblies. * **Extended Life:** While 3,000 hours may seem short, this rating is at the maximum temperature (105°C). In standard operating conditions (e.g., 40-50°C), the lifespan extends significantly (often exceeding 10+ years). ### 3. Safety Mechanism The top of the aluminum can features a "vent" (a scored cross). In the event of an internal failure or overpressure, this vent breaks safely to release gas, preventing the capacitor from exploding. --- ## Common Applications Because of its voltage rating (200V) and capacitance (560 µF), this part is typically used in the **Primary (High Voltage) stage** of power electronics: * **Switching Power Supplies (SMPS):** Acting as a bulk filter capacitor after the bridge rectifier. * **Uninterruptible Power Supplies (UPS):** Providing energy storage during power transitions. * **Industrial Inverters:** Filtering DC bus voltage for motor drives. * **Audio Amplifiers:** Used in the power reservoir section of high-wattage amplifiers. --- ## Part Number Breakdown (Typical Panasonic Logic) | Code | Meaning | | :--- | :--- | | **ECO** | Panasonic Series Prefix (Large Can) | | **S** | Snap-in Type | | **2D** | Voltage Code (200V) | | **B** | Series Identifier (TS-ED) | | **561** | Capacitance Code (56 + one zero = 560µF) | | **DA** | Case Size / Packaging code |
