The **LTCEC-13502-R** is a specific series/part number typically associated with high-frequency power inductors or magnetic components used in DC-DC converters and power management modules. --- ## 1. Component Overview This component belongs to the category of **Surface Mount (SMD) Power Inductors**. It is designed to handle high current while maintaining a compact footprint, making it ideal for modern high-efficiency power supplies. ### Key Specifications (Typical) | Feature | Description | | :--- | :--- | | **Inductance** | Typically represented by the numerical code (e.g., 13.5µH or 0.135µH depending on series scaling). | | **Mounting Type** | Surface Mount Device (SMD/SMT). | | **Material** | Composite powdered iron or ferrite core for low core loss. | | **Shielding** | Usually magnetically shielded to reduce Electromagnetic Interference (EMI). | | **Application** | VRM (Voltage Regulator Modules), Point-of-Load (POL) converters. | --- ## 2. Technical Characteristics ### Magnetic Performance * **Saturation Current ($I_{sat}$):** These inductors are engineered to have a "soft" saturation characteristic, meaning the inductance does not drop abruptly when the current exceeds the rated limit. * **DC Resistance (DCR):** Designed with very low DCR to minimize power dissipation (heat) and improve overall system efficiency. ### Thermal Management The "R" suffix often denotes **RoHS compliance** (Restriction of Hazardous Substances), ensuring the part is lead-free and suitable for high-temperature reflow soldering processes. --- ## 3. Common Applications These parts are found in demanding electronic environments, including: 1. **Computing:** Graphics cards (GPUs), servers, and high-performance motherboards. 2. **Telecommunications:** Network switches and routers requiring stable power delivery. 3. **Industrial:** Compact power modules where space is limited but current demand is high. --- ## 4. Part Number Breakdown (Generic) While naming conventions vary by manufacturer (such as Coilcraft or Bourns), the code usually follows this logic: ```text LTCEC - 13502 - R | | | Series Size/ RoHS Code Value Compliant ``` ---
