Würth Elektronik has introduced the WE-SFIA series of SMT flat wire inductors developed for automotive power electronics and high current vehicle applications.
The new component family is available in 2010, 2013 and 2016 package sizes and is designed for use in high efficiency DC/DC converters, including single and multiphase architectures, as well as buck and boost converter applications.
According to the company, the inductors support saturation currents of up to 150 A and operate within a temperature range from -40°C to +180°C. Target applications include battery management systems, motor controls, automotive audio and infotainment systems.
The WE-SFIA series uses flat wire winding technology, which improves current carrying capability while reducing DC resistance and thermal losses. Compared to conventional round wire designs, flat wire configurations also provide improved heat dissipation and increased mechanical robustness in high vibration automotive environments.
Würth Elektronik states that optimized core materials improve magnetic saturation performance while supporting compact and energy efficient system designs. The inductors are currently available in values ranging from 0.33 µH to 4.7 µH, with additional variants available for customer specific requirements.
The launch reflects growing demand for compact and thermally efficient power electronics components supporting electrification and energy management systems in modern commercial vehicle platforms.
