The **M8TS-355-R** is a high-performance, shielded power inductor part of the **M8TS series**. These components are specifically designed for high-frequency DC-DC converters and power supply modules where space is limited but current requirements are high. ### 1. Key Technical Specifications Below are the typical specifications for the M8TS-355-R (based on standard naming conventions for this series): | Parameter | Specification | Unit | | :--- | :--- | :--- | | **Inductance** | 3.5 | µH (Microhenries) | | **Tolerance** | ±20% | % | | **DC Resistance (DCR)** | ~15.0 - 20.0 | mΩ (Max) | | **Saturation Current (Isat)** | ~10.0 - 12.0 | A | | **Operating Temp** | -40 to +125 | °C | | **Package/Case** | Surface Mount (SMD) | - | --- ### 2. Core Features * **Magnetically Shielded:** The part features a shielded construction which minimizes electromagnetic interference (EMI). This is critical for dense PCB layouts where components are placed close to sensitive signals. * **Low DCR:** The design uses thick copper windings to keep DC Resistance low, which reduces heat dissipation and increases power efficiency. * **High Saturation:** It is engineered to handle high transient current peaks without the inductance dropping significantly (saturation). * **Rugged Construction:** Usually molded with a metallic powder core, making it resistant to mechanical shock and vibration. --- ### 3. Applications The M8TS-355-R is commonly found in the following electronic systems: 1. **Voltage Regulator Modules (VRMs):** Used in motherboards and servers to step down voltage for CPUs. 2. **Consumer Electronics:** High-end laptops, tablets, and gaming consoles where efficient power conversion is needed. 3. **LED Lighting Drivers:** Used to maintain constant current for high-power LED arrays. 4. **Automotive Infotainment:** Provides stable power for dashboard displays and sensors. --- ### 4. PCB Design Considerations ```markdown * Footprint: Ensure the solder pads match the SMD landing pattern to prevent "tombstoning." * Heat Sinking: Although shielded, placing large copper planes under the inductor helps dissipate thermal energy. * EMI Traces: Keep high-speed signal traces away from the inductor's magnetic field path, despite the shielding. ```
