The **LTCEC-1400F-R/Q** refers to a high-performance series of **Chip Aluminum Electrolytic Capacitors**, typically manufactured by brands like **Lelon** or similar passive component specialists. These components are designed for surface-mount technology (SMT) and are characterized by their "Low Impedance" and "Extra Lower ESR" properties. --- ### 1. Technical Specifications Overview | Parameter | Details | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor (V-Chip) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Series Features** | Low Impedance, Long Life, High Ripple Current | | **Standard Tolerance** | ±20% at 120Hz, 20°C | | **Operating Temperature** | -55°C to +105°C (Standard for high-reliability) | ### 2. Key Part Number Breakdown (Functional Logic) While specific internal codes can vary by manufacturer, the nomenclature generally follows this structure: * **LT / LTC:** Series prefix indicating "Low Impedance" and "High Temperature" characteristics. * **1400:** Often relates to the **Capacitance Value** (e.g., 1400µF) or a specific physical dimension code. * **F:** Voltage Rating code (e.g., F often represents 6.3V or 35V depending on the manufacturer's code sheet). * **R/Q:** Packaging and Quality indicators. * **R:** Tape & Reel packaging. * **Q:** Often denotes AEC-Q200 compliance (Automotive grade) or a specific lead-free/RoHS requirement. ### 3. Electronic Characteristics 1. **Low ESR (Equivalent Series Resistance):** The "EC" in the suffix often highlights "Extra Low" ESR. This minimizes heat generation during high-frequency switching, making them efficient for power conversion. 2. **High Ripple Current Handling:** Designed to withstand the AC component of the current in DC circuits without degrading the electrolyte. 3. **V-Chip Construction:** The "vertical" chip design allows for automated pick-and-place assembly while maintaining a small footprint on the PCB compared to radial leaded capacitors. --- ### 4. Common Applications These parts are typically found in demanding electronic environments: * **DC-DC Converters:** For smoothing and filtering output voltage. * **Automotive Electronics:** Used in infotainment and ADAS modules due to the wide temperature range. * **Industrial Power Supplies:** Where long-term stability and low impedance are critical. * **Telecommunications:** In base stations and networking hardware. ---
