The **LTPE-12-R** is a specific electronic component primarily recognized as a **low-voltage power inductor** or an **SMD (Surface Mount Device) power inductor**. It is commonly utilized in power management circuits for high-efficiency energy storage and filtering. --- ## 1. Technical Specifications The "LTPE" series is typically designed for high-current applications where small form factors are required. | Feature | Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Core Material** | Composite Metal Powder / Ferrite (depending on specific revision) | | **Shielding** | Magnetically Shielded (reduces EMI) | | **Operating Temp** | -40°C to +125°C (standard range) | --- ## 2. Key Electronic Characteristics The LTPE-12-R is engineered with specific electronic properties to handle high-frequency switching: ### A. Low DCR (DC Resistance) The internal copper windings are designed to have minimal resistance. This reduces power loss through heat, making the component highly efficient for battery-operated devices. ### B. High Saturation Current ($I_{sat}$) The "R" suffix often denotes a specific tolerance or RoHS compliance. These inductors can handle significant current spikes without the magnetic core "saturating," which would otherwise cause the inductance to drop sharply. ### C. EMI Suppression Because it is a shielded inductor, the magnetic field is contained within the body of the part. This prevents interference with neighboring sensitive components on the PCB (Printed Circuit Board). --- ## 3. Common Applications The LTPE-12-R is generally found in the following electronic modules: * **DC-DC Converters:** Used in "Buck" (step-down) or "Boost" (step-up) regulators. * **Voltage Regulator Modules (VRMs):** Found near CPUs and GPUs in laptops and servers. * **Portable Electronics:** Smartphones and tablets where space is limited but power demands are high. * **LED Drivers:** Providing stable current to high-brightness LED arrays. --- ## 4. Typical Footprint (Dimensions) The "12" in the part number usually refers to the physical size (e.g., 12mm x 12mm or a specific manufacturer-coded size). ```text [ Top View ] [ Side View ] _______ _______ | | | | | 1R0 | <--- Mark |_______| |_______| [__] [__] <--- Solder Pads ``` ---
