The **FDV0618-H-R24N** is a high-performance fixed inductor manufactured by **Murata Electronics** (specifically part of their TOKO heritage line). It is designed primarily for power management applications where high efficiency and low profile are critical. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±30% | | **DC Resistance (DCR)** | 1.8 mΩ (Max) | | **Rated Current (Isat)** | 22.8 A (Saturation current) | | **Rated Current (Itemp)** | 16.2 A (Temperature rise current) | | **Dimensions (L x W)** | 7.2 mm x 6.7 mm | | **Height (Max)** | 1.8 mm | | **Operating Temperature** | -40°C to +125°C | --- ## 2. Key Features and Construction ### Metal Alloy Core Unlike standard ferrite inductors, the FDV series uses a **metal alloy powder** core. This construction provides: * **Soft Saturation:** The inductance drops gradually as current increases, rather than dropping sharply. * **High Current Handling:** It can manage high peak currents relative to its small physical size. ### Magnetic Shielding The component is magnetically shielded. This prevents electromagnetic interference (EMI) from leaking out and affecting neighboring sensitive components on the PCB, and it also reduces the likelihood of the inductor picking up noise. ### Low Profile With a maximum height of only **1.8 mm**, it is ideal for thin electronic devices like ultrabooks, tablets, and slim power modules. --- ## 3. Common Applications Due to its high current capacity and low DCR, the FDV0618-H-R24N is typically used in: 1. **DC-DC Converters:** Voltage Regulator Modules (VRM) for CPUs and GPUs. 2. **Point of Load (PoL):** Localized power regulation on high-density circuit boards. 3. **Battery Powered Devices:** High efficiency ensures longer battery life due to minimal energy loss through resistance. 4. **Automotive Infotainment:** Suitable for rugged environments requiring high heat tolerance. --- ## 4.
