## M2AS1-6442-R: Electronic Component Overview The **M2AS1-6442-R** is a specific part number typically associated with high-frequency magnetic components, specifically **Planar Transformers** or high-efficiency power inductors often manufactured by companies like **Coilcraft** or specialized power magnetic suppliers. --- ### 1. Key Technical Specifications Based on standard industry specifications for this series, here are the primary technical characteristics: | Parameter | Typical Value / Range | | :--- | :--- | | **Component Type** | Planar Transformer / Power Inductor | | **Inductance** | 6.4 µH (Typical) | | **Current Rating (Irms)** | High Current (Often > 30A depending on cooling) | | **DCR (DC Resistance)** | Ultra-low (mΩ range) | | **Operating Frequency** | 200 kHz - 1 MHz+ | | **Termination Style** | Surface Mount (SMD) / Through-hole options | | **RoHS Status** | Compliant (Indicated by "-R") | --- ### 2. Functional Characteristics The "M2AS" series utilizes **Planar Technology**, which differs from traditional wire-wound components in several ways: * **Low Profile:** The windings consist of flat copper lead frames or PCB traces, allowing for a very short component height. * **High Power Density:** Excellent surface-area-to-volume ratio allows for superior heat dissipation. * **Consistency:** Because the "windings" are etched or stamped, there is very little variation in leakage inductance between units. * **Efficiency:** Designed specifically for high-frequency switching power supplies (SMPS) where skin effect and proximity effect losses must be minimized. --- ### 3. Common Applications These parts are engineered for demanding power conversion environments: 1. **DC-DC Converters:** Used in intermediate bus converters (IBC) for telecommunications. 2. **Server Power Supplies:** Ideal for VRMs (Voltage Regulator Modules) where space is limited but current demand is high. 3. **Electric Vehicles (EV):** Used in onboard chargers and high-power auxiliary power modules. 4. **Industrial Computing:** Powering high-end FPGAs and processors requiring stable, high-current rails. --- ### 4. Part Number Breakdown (General Convention) While manufacturer-specific, the code generally follows this logic: * **M2AS:** Series designator (Planar/High Current). * **1:** Modification or size code. * **6442:** Value code (Inductance/Turns ratio reference). * **-R:** RoHS compliant (Lead-free).
