500 V power inductors are AEC-Q200-qualified
Sumida is using the 2024 APEC Power Electronics Conference for the North American introduction of two new series of AEC-Q200 qualified power inductors, the DPQ3535/T150 and DPQ5050/T150. These inductors are magnetically shielded and have a pin-type base for surface mounting on printed circuit boards. High surface area flat-wire windings minimize internal resistance at high frequencies […]
SMD power inductors handle high temperatures, high currents
Sumida continues the expansion of its AEC-Q200 qualified SMD inductors with the introduction of the CDEP13D**/T150 line. Consisting of ten standard types and ten high-power types, the new devices offer a combination of four key benefits, when compared to many other inductors. These are high temperature, high current, high-insulation voltage, and magnetic shielding. Inductance values range from […]
High-temperature SMD power inductors target automotive/industrial uses
Growth in demand for high-temperature automotive and industrial circuitry has sparked Sumida to greatly expand its lineup of AEC-Q200 qualified SMD inductors. In early 2019, Sumida introduced the CDRH50D28B/T150 Series of high temperature shielded drum and ring core inductors, for a range of automotive applications. Five additional package sizes have now been added to the […]
Magnetically shielded inductors perform in class D amplifiers
Sumida’s magnetically shielded DEP1519B Series Power Inductors are designed for applications in class D digital audio amplifiers, as well as in dc/dc converters and other low-pass filter applications. To minimize internal resistance at high frequencies, high surface area flat-wire is used for the windings. The flat wires also allow more compact construction with higher current […]
Shielded drum inductors target automotive apps
The new CDRH50D28B/T150 Shielded Drum inductor for a broad range of automotive applications is based on Sumida’s Ni-Zn ferrite core technology, this power inductor is highly space-efficient and complies with automotive reliability standard, AEC-Q200. It is applicable to ADAS and other automotive applications which require a small footprint and high-inductance value (max. 100 µH). Product […]
Gallery: Cool tech demos at APEC2018, IEEE’s Applied Power Electronics Conference and Exposition
APEC is considered the premier forum for power electronics developments in the U.S. Recently concluded in San Antonio, Tex., the conference and exposition focused on the practical and applied aspects of the power electronics business. In the pages that follow are a few interesting displays that could be found on the exposition floor. NEXT PAGE: […]
Magnetically shielded SMD power inductors for high inductances
Metal Hybrid Inductors, known as the CDMT40 series, offer more than double the inductance values of earlier introductions while maintaining the same small footprint. A newly developed composite material draws on the special qualities of two different metals in the mold structure to provide magnetic shielding, small size, and high current ratings. The CDMT40D40 also […]
Gallery: APEC 2017 — Hot markets moving cool speed ahead
A considerable segment of the products and technology at the Applied Power Electronic Conference (APEC) 2017 would have fit right in or neatly alongside a 2017 auto and telecom show. Power electronics for EV on- and off-board chargers were making headlines, as well as electronics addressing the high-speed server markets. Silicon Carbide (SiC) and Gallium […]
SMD Isolation Transformer for Vehicle Battery Monitoring, High-Speed Modems
The Sumida ESMIT-4180/C Series Isolation Transformer is the latest entry into Sumida’s line of low-profile, surface-mounted isolation transformers. It was developed to better respond to the demands of the embedded-circuit based products, including automotive battery monitoring, high-speed modems and other circuits. As an example, the ESMIT-4180/C is included in the reference design for the NXP […]
