The **LAM-1641-R82K-F** is a specific electronic component, typically categorized as a **Fixed Inductor** (Surface Mount Device - SMD). It is commonly used in high-frequency circuits, power management, and signal filtering. --- ### 1. Technical Specifications Below are the typical parameters associated with this part number (based on standard naming conventions for the LAM series): | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.82 µH | Indicated by the code "R82" | | **Tolerance** | ±10% | Indicated by the "K" suffix | | **Type** | Fixed Inductor | Wire-wound or Multilayer ceramic/ferrite | | **Mounting Type** | Surface Mount (SMD) | Designed for PCB soldering | | **Packaging** | Tape & Reel | Standard for automated assembly | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying its characteristics: * **LAM**: Series identifier (usually referring to high-frequency or miniature power inductors). * **1641**: Physical dimensions or series size (typically 1.6mm x 0.8mm or similar proprietary sizing). * **R82**: Inductance value. The "R" acts as a decimal point. **R82 = 0.82 µH**. * **K**: Tolerance code. **K = ±10%** (J would be ±5%, M would be ±20%). * **F**: Lead-free / RoHS compliant designation. --- ### 3. Common Applications These components are generally found in the following electronic environments: 1. **RF Circuits:** Used for impedance matching or frequency tuning in wireless communication devices. 2. **DC-DC Converters:** Acts as an energy storage element in miniature power supply modules. 3. **EMI Filtering:** Suppresses high-frequency noise in sensitive signal lines. 4. **Mobile Electronics:** Due to its small form factor, it is ideal for smartphones, tablets, and wearables. --- ### 4. Key Performance Factors When integrating this part into a circuit, engineers look at: * **Self-Resonant Frequency (SRF):** The frequency at which the part stops acting like an inductor. * **DC Resistance (DCR):** The internal resistance of the coil; lower is better for efficiency. * **Saturation Current ($I_{sat}$):** The current level where inductance drops by a specific percentage.
