AC challenges with inductors
To get good performance from inductors in power supplies, you need to be careful about the AC characteristics. Physical inductors are complex structures, not ideal components. And the AC challenges with inductors are growing due to the higher operating frequencies of power supplies using silicon carbide (SiC) and gallium nitride (GaN) power switches. This FAQ […]
Thin-film power inductors target automotive power circuits
TDK Corporation has developed a series of thin-film metal power inductors for automotive power circuits. The new TFM201210ALMA inductors feature a mounting area downsized approximately 22 % from TDK’s conventional product, TFM201610ALMA (2.0 mm (L) x 1.6 mm (W) x 1.0 mm (H)). Mass production will begin in August 2021. Demand has recently increased in […]
