The **MA2HTCX-R** is a high-performance, shielded power inductor manufactured by **Eaton (formerly Coiltronics)**. It is part of the **MPIA2 (Automotive-grade)** or **MA2** series, specifically designed for high-current power conversion in compact electronic devices. --- ### 1. Key Technical Specifications The part number "MA2HTCX-R" follows a specific naming convention that defines its electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Inductance** | Typically ranges from 0.10µH to 10µH (depends on sub-code) | | **Core Material** | Metal Composite (Low EMI / Soft Saturation) | | **Shielding** | Magnetically Shielded | | **Operating Temp** | -40°C to +125°C (AEC-Q200 Qualified) | | **Tolerance** | ±20% | | **Packaging** | Tape and Reel (indicated by the "-R") | --- ### 2. Physical & Material Construction * **Metal Composite Core:** Unlike traditional ferrite cores that saturate abruptly, the metal composite core allows for "soft saturation." This means the inductance drops gradually as current increases, preventing sudden circuit failure. * **Molded Construction:** The wire is embedded directly into a metallic powder mixture. This results in a rugged, compact package with excellent heat dissipation. * **Magnetic Shielding:** The design minimizes electromagnetic interference (EMI), which is critical for sensitive components located nearby on a PCB. --- ### 3. Features & Applications The MA2HTCX-R is engineered for high-density power applications where space is limited and reliability is paramount. #### Primary Features: 1. **High Current Handling:** Capable of managing high peak currents relative to its small footprint. 2. **Low DCR (DC Resistance):** Reduces power loss and heat generation, increasing overall system efficiency. 3. **AEC-Q200 Grade:** Validated for automotive use, ensuring high resistance to mechanical shock and vibration. #### Common Applications: * **Automotive Electronics:** Infotainment systems, ADAS (Advanced Driver Assistance Systems), and LED lighting. * **Portable Devices:** Tablets, smartphones, and handheld gaming consoles. * **DC-DC Converters:** Used as a smoothing inductor in Buck, Boost, or SEPIC converters. --- ### 4. Part Number Breakdown (Example) * **MA2:** Series name (Molded Power Inductor, Automotive Grade). * **HT:** High Temperature/High Performance variant. * **CX:** Specific case size/mechanical dimensions. * **-R:** RoHS compliant and Tape & Reel packaging.
