The **2662-R** typically refers to a high-performance **Surface Mount (SMD) Power Inductor**, commonly manufactured by companies like **Delevan** or as part of specific power management series. These components are designed for high-frequency applications and robust power handling. --- ### 1. Key Technical Specifications Below are the general electrical and physical characteristics associated with the 2662-R series inductors: | Feature | Specification | | :--- | :--- | | **Component Type** | Power Inductor (Shielded/Unshielded) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Inductance Range** | Typically ranges from 1.0µH to 1000µH (varies by suffix) | | **Current Rating** | High Saturation Current (up to several Amps) | | **Operating Temp** | -55°C to +125°C | | **Core Material** | Ferrite or Powdered Iron | --- ### 2. Physical Construction The "2662" designation often refers to the **Package Size** or the series footprint. * **Dimensions:** Usually follows a standard metric or imperial footprint (e.g., approximately 6.6mm x 4.45mm, though this varies by manufacturer). * **Termination:** Features solderable end-caps or leads designed for automated "pick and place" assembly. * **The "-R" Suffix:** In the electronics industry, the suffix **-R** almost universally stands for **RoHS Compliant** (Lead-Free), ensuring the part meets environmental safety standards. --- ### 3. Common Applications Because of its ability to handle high current and store magnetic energy efficiently, the 2662-R is used in: 1. **DC-DC Converters:** Acts as an energy storage element in buck or boost regulators. 2. **Noise Filtering:** Used in power lines to suppress high-frequency electromagnetic interference (EMI). 3. **Voltage Regulation Modules (VRM):** Found on motherboards and graphics cards to stabilize power delivery to CPUs/GPUs. 4. **Telecommunications:** Used in base stations and networking hardware for signal integrity and power management. --- ### 4. Example Part Number Breakdown If you see a full part number like `2662-102-R`, it is decoded as follows: * **2662:** The Series/Case Size. * **102:** The Inductance value (10 + two zeros = 1000µH). * **R:** RoHS Compliant.
