The **ECST1V0504-1125-R** is a specific electronic component, likely categorized as a **Surface Mount Device (SMD) Multilayer Ceramic Chip Capacitor (MLCC)** or a similar specialized passive component. Based on industry naming conventions, here is the breakdown of its specifications and characteristics. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Multilayer Ceramic Capacitor (MLCC) | | **Package / Case** | 0504 (Inch) or similar metric equivalent | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Voltage Rating** | 35V (Indicated by "1V") | | **Packaging** | Tape & Reel (Indicated by "-R") | --- ### 2. Part Number Breakdown While manufacturer codes vary, the typical breakdown for this part series follows this logic: * **ECST**: Series prefix (Often associated with specific dielectric stability or low-profile designs). * **1V**: Voltage Code. In standard electronics, "1V" typically represents a **35V** DC rating. * **0504**: Physical dimensions. This indicates a length of 0.05 inches and a width of 0.04 inches. * **1125**: This often refers to the capacitance value or a specific manufacturing lot code. If representing capacitance, it follows a 3-digit code (e.g., 112 = 1.1nF). * **-R**: RoHS compliant and supplied on a Tape & Reel for automated assembly. --- ### 3. Key Characteristics * **Compact Footprint**: The 0504 size is small, making it ideal for high-density circuit boards like those found in smartphones, wearables, and IoT devices. * **High Stability**: Components in this series are usually designed for bypass, decoupling, or filtering applications where space is at a premium. * **Temperature Coefficient**: These parts are typically rated for operation between **-55°C to +125°C**, depending on the dielectric material (e.g., X7R or X5R). --- ### 4. Common Applications 1. **Power Management**: Decoupling high-frequency noise in DC-DC converters. 2. **Consumer Electronics**: Used in laptops, tablets, and handheld devices. 3. **Automotive**: If AEC-Q200 qualified, used in infotainment and sensor modules. 4. **Telecommunications**: Signal smoothing in base station equipment.
