Signal SHFWT Series Delivers Superior Efficiency, Thermal Performance and Low EMI noise in High-Frequency Toroidal Inductors

Signal today announced the introduction of its SHFWT Series Helical Wound Flat Wire Toroidal Inductors, broadening the Signal portfolio with a high-performance solution for demanding electronic designs. The SHFWT Series strengthens Signal's lineup of chokes, coils, and inductors, responding to increasing demand for efficient, low-loss, high-frequency power components.

The low profile SHFWT Series uses an edge-wound flat copper wire construction that allows more turns in a single winding layer. This approach reduces inter-winding capacitance skin and proximity effects, delivering lower AC resistance and improved performance at higher frequencies. Paired with high-grade core materials, the design minimizes overall power loss and heat generation. Both vertical and horizontal mounting options support flexible integration across diverse system architectures.

"Engineers designing compact, power-dense systems face real challenges managing thermal dissipation and efficiency at higher switching frequencies," said Anthony Kourtessis, Design Engineer. "The SHFWT Series addresses this directly, the single-layer flat wire construction and premium core materials work together to keep losses low without compromising on inductance or current handling capability."

The SHFWT Series is engineered for demanding applications across data centers, industrial power electronics, telecom, automotive, and renewable energy sectors. Typical applications include switching power supplies, UPS systems, high power DC-DC converters, battery chargers, and energy storage inverters where efficiency and thermal performance are critical.
