The **MAH14FAG-R** is a high-performance, shielded power inductor typically manufactured by companies like **Mag.Layers**. These components are essential in modern electronics for energy storage and noise filtering within power management circuits. --- ### 1. Technical Specifications Below is a breakdown of the typical technical parameters for the MAH14FAG-R series: | Parameter | Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Inductance** | Varies by sub-model (Commonly 1.0µH to 4.7µH) | | **Tolerance** | ±20% (Standard for power inductors) | | **DCR (Direct Current Resistance)** | Low resistance to minimize power loss | | **Current Rating** | High saturation current capability | | **Shielding** | Magnetic Resin / Metal Composite Shielding | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Key Electronic Features * **Magnetic Shielding:** The "shielded" construction prevents electromagnetic interference (EMI) from affecting surrounding components. This is critical in compact PCB designs. * **Low Profile:** Designed for space-constrained applications like smartphones, tablets, and wearable tech. * **Saturation Characteristics:** These inductors are engineered to handle high peak currents without the inductance dropping significantly (soft saturation). * **Efficiency:** The low DCR ensures that very little energy is wasted as heat, which extends battery life in portable devices. --- ### 3. Common Applications The MAH14FAG-R is widely used in DC-DC converter circuits. Specifically: 1. **Buck/Boost Converters:** Used as the energy storage element to step voltage up or down. 2. **Power Management Integrated Circuits (PMICs):** Found in the power stages of processors and GPUs. 3. **Consumer Electronics:** Used in laptops, SSDs, and handheld gaming consoles. 4. **Telecommunications:** Noise filtering in high-speed data modules. --- ### 4. Part Number Breakdown (Example) While manufacturers have unique codes, the "MAH" series generally follows this logic: ```text MAH - 14 - FAG - R | | | | | | | +-- RoHS Compliant / Tape & Reel Packaging | | +------- Material/Internal Design Code | +------------- Case Size (e.g., 1.4mm x 1.2mm) +------------------ Product Series (Metal Alloy High Current) ```
