Brückewell introduces SiC product series

In the recent decades, the Silicon carbide (SiC), turned out to be an excellent semiconductor material. Composed of carbon and silicon, it has been used in power applications, in which showed excellent performance, far superior to those of silicon.

Significant progress has been made in the field of the semiconductor industry, allowing the development of more and more sophisticated technologies for silicon carbide processing, which have resulted in semiconductor devices with excellent performance.

In facts, those devices have shown a remarkable capacity to reduce losses and a high switching speed in comparison to that offered by silicon. The use of silicon carbide (SiC) as a semiconductor begins to expand into multiple applications and is increasingly becoming the most suitable candidate to replace silicon in applications such as automotive and E-Bike motor control.

For these reasons, Bruckewell Semi decided to launch the production of the SiC Products, including the SiC Schottky Diode and SiC MOSFET, support the 650V to 1200V, and give the opportunity to its customers to take advantage of the benefits of SiC high-voltage power applications.

Fastron News XHBHV – A leaded axial inductor designed to operate at voltage levels up to 400V




In addition to FASTRON’s standard leaded axial inductors the specialist adds a new ‘high voltage’ leaded axial inductor to the company’s product portfolio. Utilizing a special winding wire and a new coating, the choke can operate at voltage levels up to 400V and can withstand higher peak-voltage. Using a ferrite core the XHBHV choke offers inductance values from 100µH to 6800µH, ± 5% tolerance, maximum DCR from 0.22Ω to 14.16Ω, and current ratings (I1) from 0.22A to 1.76A.

The XHBHV inductors are a supplement to the standard leaded axial inductors for designs which are directly connected to the power line. Major applications for the XHBHV series are suppression of transients as well as EMC filtering in electrical motors and in switching power supplies used in home appliances, industrial, lighting, and automotive applications.
