The **MAH22FBX-R** is a high-performance, shielded power inductor manufactured by **Delta Electronics**. This component is primarily designed for high-current applications such as DC-DC converters, power supplies, and voltage regulator modules (VRMs). --- ### 1. Key Technical Specifications The following table highlights the critical electrical characteristics of the MAH22FBX-R: | Parameter | Specification | | :--- | :--- | | **Inductance** | 2.2 µH | | **Tolerance** | ±20% | | **DCR (DC Resistance)** | ~3.3 mΩ (Max) | | **Saturation Current (Isat)** | ~21.0 A | | **Heating Current (Irms)** | ~18.0 A | | **Shielding** | Magnetically Shielded | | **Package / Case** | SMD (Surface Mount Device) | --- ### 2. Core Electronic Features * **Metal Alloy Core:** Unlike traditional ferrite inductors, the MAH series uses a metal alloy composite material. This allows for a "soft" saturation characteristic, meaning the inductance decreases gradually as current increases rather than dropping off sharply. * **Low DCR (DC Resistance):** By utilizing thick copper windings, the component minimizes power loss through heat, making it highly efficient for high-current power delivery. * **Magnetic Shielding:** The construction minimizes Electromagnetic Interference (EMI), which is crucial for densely packed circuit boards where signal integrity is a priority. * **AEC-Q200 Compliance (Typical):** Most parts in this series are designed to meet automotive reliability standards, offering high resistance to thermal shock and vibration. --- ### 3. Application Use Cases Due to its high current handling and compact footprint, it is commonly found in: 1. **Computing:** Motherboards, GPU power phases, and Server VRMs. 2. **Automotive:** Infotainment systems and ADAS modules. 3. **Industrial:** High-efficiency DC-DC buck/boost converters. --- ### 4. Mounting & Footprint The "R" suffix typically denotes **Tape & Reel** packaging, intended for automated pick-and-place assembly. The footprint is designed for standard reflow soldering profiles. ---
