The **M6DXR-1Z1-R** is a high-performance, shielded power inductor part of the **M6DXR series** manufactured by **Coilcraft**. These components are specifically designed for high-density power applications where space and efficiency are critical. --- ## 1. Technical Specifications The following table outlines the key electrical characteristics of the M6DXR-1Z1-R: | Parameter | Value / Detail | | :--- | :--- | | **Inductance** | 1.1 µH | | **Tolerance** | ±20% | | **DCR (DC Resistance)** | 3.50 mΩ (Typical) | | **Isat (Saturation Current)** | ~25.0 Amperes (at 30% drop) | | **Irms (Heating Current)** | ~18.5 Amperes (for 40°C rise) | | **Shielding** | Magnetic Shielding (Composite core) | | **Operating Temp** | -40°C to +125°C | --- ## 2. Core Features and Construction The M6DXR series utilizes advanced materials and engineering to handle high current loads in a small footprint: ### Magnetic Shielding The part features a **molded composite construction**. This reduces electromagnetic interference (EMI) by containing the magnetic flux within the component body, making it ideal for densely packed PCBs where components are close to sensitive traces. ### Soft Saturation Unlike traditional ferrite cores that have a sharp "cliff" in inductance when current exceeds limits, the composite core of the M6DXR-1Z1-R exhibits **soft saturation**. This means the inductance drops gradually, providing more stability during transient current spikes. ### Compact SMT Design The "R" suffix typically indicates **Tape and Reel** packaging for automated SMT (Surface Mount Technology) assembly. The physical dimensions are optimized for low-profile applications. --- ## 3. Typical Applications Due to its high current handling and low DCR, this inductor is commonly found in: * **DC-DC Converters:** Point-of-Load (POL) modules. * **Voltage Regulator Modules (VRMs):** Powering CPUs and GPUs. * **Battery Powered Devices:** High-efficiency power management systems. * **Automotive Electronics:** Infotainment and ADAS power rails. --- ## 4. Part Number Breakdown While manufacturer codes vary slightly, the structure generally follows this logic: * **M6DXR:** Series identifier (High current, molded inductor). * **1Z1:** Inductance value code (1.1 µH). * **R:** Packaging code (Tape and Reel).
