The **MP1202-8-RX** refers to a high-frequency, surface-mount (SMD) planar transformer or inductor component, typically used in high-density power conversion modules. This specific part is often associated with DC-DC converter applications where efficiency and a low profile are critical. ### 1. Technical Specifications The following table summarizes the general electrical and physical characteristics of this series: | Parameter | typical Specification | | :--- | :--- | | **Component Type** | Planar Transformer / Inductor | | **Inductance Range** | 8.0 µH (based on the "-8-" naming convention) | | **Current Rating** | Up to 12A - 20A (Application dependent) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Operating Temperature** | -40°C to +125°C | | **Core Material** | Ferrite | --- ### 2. Key Internal Components & Construction The MP1202-8-RX is designed using **Planar Technology**, which differs from traditional wire-wound components: 1. **Planar Windings:** Instead of copper wire wrapped around a bobbin, it uses stacked copper foil or printed circuit board (PCB) traces. This reduces skin effect losses at high frequencies. 2. **Ferrite Core:** A low-profile E-core or ER-core made of manganese-zinc (MnZn) or nickel-zinc (NiZn) ferrite to provide high magnetic permeability and low core loss. 3. **Termination (RX):** The "RX" suffix usually denotes the specific lead frame or pad configuration, optimized for automated pick-and-place assembly and high-reliability soldering. --- ### 3. Application Use Cases This component is primarily integrated into the following electronic systems: * **Point of Load (POL) Converters:** Used in telecommunications to step down voltage near the CPU or FPGA. * **Isolated DC-DC Supplies:** Acts as the primary magnetic element for power transfer. * **High-Efficiency Inverters:** Its low profile makes it ideal for slim electronic devices like laptops or industrial tablets. --- ### 4. Implementation Example (Schematic Logic) In a typical buck or forward converter circuit, the part functions as the energy storage element: ```spice * Simplified Buck Converter Fragment VIN 1 0 DC 12V SW 1 2 MOD1 ; Switching Transistor L1 2 3 8uH ; MP1202-8-RX Inductor C1 3 0 100uF ; Output Capacitor RL 3 0 10 ; Load ``` ---
