The part number **ECOS2DB561BA** refers to a high-performance **Aluminum Electrolytic Capacitor** manufactured by **Panasonic**. It belongs to the **TS-HB Series**, which is designed for high voltage and compact snap-in mounting. --- ## 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the ECOS2DB561BA: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Panasonic | | **Capacitance** | 560 µF | | **Voltage Rating** | 200 VDC | | **Tolerance** | ±20% | | **Temperature Range** | -40°C to +105°C | | **Lifetime (Endurance)** | 3000 Hours @ 105°C | | **Termination Style** | Snap-In (2 Pins) | | **Mounting Type** | Through Hole | | **Dimensions** | 22mm (Diameter) x 45mm (Length) | --- ## 2. Key Features * **Snap-in Terminals:** The leads are designed to "snap" into a PCB, holding the component in place before soldering. This is ideal for automated assembly. * **High Ripple Current:** Designed to handle significant AC current superimposed on the DC voltage, which is critical for power supply stability. * **105°C Rating:** Unlike standard 85°C capacitors, this model is rated for higher temperatures, ensuring a longer lifespan in heat-intensive environments. * **Compact Size:** The TS-HB series utilizes advanced foil etching technology to achieve high capacitance in a smaller footprint. --- ## 3. Applications Due to its voltage rating (200V) and capacitance (560µF), this part is commonly found in the following circuits: 1. **Switching Power Supplies (SMPS):** Used as a bulk storage capacitor in the input filtering stage. 2. **AC/DC Converters:** Smoothes rectified DC voltage. 3. **Motor Drives:** Provides energy storage for industrial motor controllers. 4. **Uninterruptible Power Supplies (UPS):** Used in the power conversion stages. --- ## 4. Replacement Considerations If you are looking for a replacement or equivalent, ensure the following parameters match or exceed the original: * **Voltage:** Can be higher than 200V, but never lower. * **Capacitance:** Should be as close to 560µF as possible (usually within ±20%). * **Pitch (Lead Spacing):** Ensure the snap-in pins match your PCB layout (typically 10mm for this size). * **Physical Height:** Check for vertical clearance in the enclosure.
