The **LTCEC-11252-R** is a specific electronic component typically categorized as a **Surface Mount (SMT) Inductor**, often utilized in power management and signal filtering circuits. Below is a detailed technical breakdown of its characteristics and functions. --- ### 1. Component Overview The "LTCEC" series generally refers to high-current, low-profile power inductors. These are designed to handle significant current while maintaining a small footprint on a Printed Circuit Board (PCB). | Feature | Description | | :--- | :--- | | **Component Type** | Power Inductor / Fixed Inductor | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Core Material** | Ferrite or Metal Alloy (shielded) | | **Typical Application** | DC-DC Converters, Voltage Regulator Modules (VRM) | --- ### 2. Technical Specifications While exact values can vary slightly by manufacturer (often associated with brands like **LTC** or specialized magnetic suppliers), the "11252" designation usually refers to the physical dimensions. * **Physical Size:** Approximately 11mm x 11mm (or 12mm) with a specific height (often denoted by the last digits). * **Inductance Value:** Usually specified in Microhenries (µH). In many naming conventions, the "R" indicates a decimal point or a specific tolerance/revision. * **Shielding:** Most parts in this series are **Magnetic Shielded**, which reduces Electro-Magnetic Interference (EMI) with neighboring components. --- ### 3. Key Functions in a Circuit The LTCEC-11252-R serves several critical roles in electronic assemblies: 1. **Energy Storage:** In switching power supplies, it stores energy in its magnetic field during the "on" cycle and releases it during the "off" cycle. 2. **Ripple Filtering:** It smoothes out the current ripples in DC-DC converters to provide a stable output voltage. 3. **Noise Suppression:** It acts as a low-pass filter, blocking high-frequency AC noise while allowing DC current to pass through. --- ### 4. Common Use Cases These inductors are frequently found in high-performance hardware, including: * **Server Motherboards:** Managing high-current CPU power phases. * **Graphics Cards (GPUs):** Filtering power for high-speed memory and processing cores. * **Industrial Power Supplies:** Providing robust power regulation in harsh environments. --- ### 5. Identification Code Breakdown | Segment | Meaning | | :--- | :--- | | **LTCEC** | Series/Manufacturer code (Low Temperature/High Current Inductor) | | **11252** | Case size (Dimensions in mm) | | **-R** | Often signifies "RoHS Compliant" (Lead-free) or a specific Tape & Reel packaging |
