### MP2A-150-R: Electronic Components & Specifications The **MP2A-150-R** is a high-performance, shielded power inductor belonging to the **MPI (Molded Power Inductor)** series, typically manufactured by **Eaton (formerly Cooper Bussmann)**. It is designed for high-current applications where space is limited and efficiency is critical. --- ### 1. Key Technical Specifications The following table outlines the core electronic parameters for the MP2A-150-R: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 15.0 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | ~1.6 Amperes (Typical) | | **Saturation Current (Isat)** | ~2.5 Amperes (Typical) | | **DC Resistance (DCR)** | ~240 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | Surface Mount (SMD) - 2.0mm height | --- ### 2. Core Internal Composition The device is built using a **molded construction** method. This involves several critical sub-components: * **Magnetics:** It utilizes a metal flake powder core. This material allows for higher saturation currents compared to traditional ferrite cores and provides a "soft saturation" characteristic. * **Winding:** A precision copper coil is embedded directly into the molded body, minimizing the distance between the inductor and the PCB to reduce EMI. * **Shielding:** The molded body acts as a natural magnetic shield, significantly reducing electromagnetic interference (EMI) with neighboring components. --- ### 3. Application Areas Because of its small footprint and high efficiency, the MP2A-150-R is commonly found in the following electronic circuits: 1. **DC-DC Converters:** Used in "Buck" (step-down) or "Boost" (step-up) regulators. 2. **Portable Electronics:** Ideal for smartphones, tablets, and handheld medical devices due to the low-profile (2.0mm height). 3. **Computing:** Voltage Regulator Modules (VRMs) for low-power CPUs and memory modules. 4. **Battery Powered Systems:** Where low DCR is required to maintain long battery life. --- ### 4.
