The **AS50-R15K-RC** is a precision power inductor part of the AS50 series. These components are primarily used for energy storage, filtering, and smoothing in electronic power circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers (typically associated with brands like **Allied Components**). Below are the key technical parameters: | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.15 µH (Microhenries) | | **Tolerance** | ±10% (K) | | **Core Material** | Carbonyl Iron / Composite | | **Package Type** | Surface Mount Device (SMD) | | **RoHS Compliant** | Yes (-RC suffix) | --- ### 2. Physical Construction The "AS50" designation usually refers to the physical footprint of the inductor. * **Shielding:** These are typically **shielded** inductors. This means the magnetic field is contained within the component, reducing Electromagnetic Interference (EMI) with neighboring parts on the PCB. * **Molded Body:** They are often constructed using a metal powder molding process, which allows for higher saturation currents compared to traditional ferrite drum cores. --- ### 3. Key Electronic Characteristics When integrating the AS50-R15K-RC into a circuit, three main factors are considered: 1. **Low DCR (DC Resistance):** Because the inductance is very low (0.15 µH), the internal resistance is extremely small. This minimizes power loss (heat) during operation. 2. **High Saturation Current ($I_{sat}$):** These parts are designed to handle high current spikes without the inductance "dropping off" or the core saturating. 3. **High Frequency Performance:** Due to the low inductance value, this part is ideal for high-frequency switching regulators (typically in the MHz range). --- ### 4. Typical Applications The AS50-R15K-RC is commonly found in the following electronic environments: * **DC-DC Converters:** Specifically "Buck" or "Boost" converters used in laptops and servers. * **Voltage Regulator Modules (VRM):** Providing stable power to CPUs and GPUs. * **High Current Power Supplies:** Where space is limited but current demand is high. * **Battery Powered Devices:** To ensure high efficiency and longer battery life. --- ### 5. Part Number Breakdown * **AS50:** Series/Size code. * **R15:** Inductance value ($R$ acts as decimal; $0.15$ µH). * **K:** Tolerance ($\pm10\%$). * **RC:** RoHS Compliant (Lead-free).
