The **CTSFW7050F-R76M** is a high-performance, shielded power inductor typically used in automotive and industrial power management circuits. It is designed to handle high currents while maintaining low electromagnetic interference (EMI). --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers (like Central Technologies). Below are the core technical parameters: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.76 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Case Size** | 7050 (Approx. 7.0mm x 7.5mm x 5.0mm) | | **Structure** | Shielded (Ferrite Core) | | **Mounting Type** | Surface Mount (SMD) | ### 2. Physical Construction The "7050" footprint refers to the physical dimensions of the component. The construction usually consists of: * **Winding:** Copper wire wound around a ferrite core. * **Shielding:** A magnetic shield (often a metal composite or ferrite sleeve) that keeps the magnetic field contained, preventing interference with nearby sensitive components. * **Terminals:** Robust Solder pads designed for reflow soldering. ### 3. Key Electronic Functions * **Energy Storage:** It stores energy in a magnetic field during the "on" cycle of a switching regulator and releases it during the "off" cycle. * **Filtering:** Acts as a low-pass filter to smooth out current ripples in DC-DC converters. * **High Current Handling:** Due to the 0.76 µH value, it is optimized for high-speed switching power supplies where low inductance allows for faster transient responses. ### 4. Typical Applications This specific inductor is commonly found in: 1. **Automotive Electronics:** Powering ADAS sensors, infotainment units, or LED lighting drivers. 2. **DC/DC Converters:** Point-of-Load (POL) power supplies for CPUs or FPGAs. 3. **Industrial Controls:** High-efficiency power modules requiring low EMI signatures. ---
