The **1094AS-R68N** is a specific surface-mount fixed inductor, typically part of the **DFE252012F** series manufactured by **Murata Electronics**. This component is widely used in power management circuits for portable electronics due to its small footprint and high efficiency. --- ### 1. Technical Specifications Below are the primary electrical and physical characteristics of the 1094AS-R68N: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±30% | | **Rated Current (Isat)** | ~4.8 A (Saturation current based on inductance change) | | **Rated Current (Itemp)** | ~3.8 A (Temperature rise current) | | **DC Resistance (DCR)** | ~29 mΩ (Max) | | **Package Size (Inch)** | 1008 | | **Dimensions (mm)** | 2.5 mm x 2.0 mm x 1.2 mm | | **Shielding** | Shielded (Magnetic Resin) | --- ### 2. Key Features * **Metal Alloy Core:** Unlike traditional ferrite inductors, these use a metal powder core which allows for better "soft saturation" characteristics (it doesn't lose inductance abruptly as current increases). * **Magnetic Shielding:** The structure is resin-shielded to minimize Electromagnetic Interference (EMI), making it safe for high-density PCB layouts. * **Low Profile:** With a height of only 1.2mm, it is ideal for slim devices like smartphones and tablets. * **High Current Capability:** Despite its small size, the metal alloy construction allows it to handle significant current levels required for DC-DC converters. --- ### 3. Common Applications This inductor is primarily designed for **DC-DC Converter** applications where voltage needs to be stepped down (Buck) or stepped up (Boost). 1. **Mobile Devices:** Power supply lines for CPUs/GPUs in smartphones. 2. **Portable Electronics:** Digital cameras, handheld consoles, and wearable tech. 3. **SSD/Storage:** Power management for Solid State Drives. 4. **IoT Modules:** High-efficiency power stages for wireless sensors. --- ### 4. Part Number Breakdown While Murata uses internal codes, the part number generally follows this logic: * **1094AS:** Series identifier (Metal Alloy Shielded). * **R68:** Inductance value (R = decimal point; 0.68 µH). * **N:** Tolerance code (typically indicating the ±30% range).
