TFM-BLEA Series Thin-Film Power Inductors

TDK Corporation TFM201612BLEA series (2.0 mm x 1.6 mm x 1.2 mm – L x W x H) thin-film power inductors for automotive power circuits now support higher currents of up to 5.6 A. The two latest components have a rated inductance of 0.33 µH and 0.47 µH, respectively.

Compared to the conventional TFM-ALMA series of the same size with an inductance of 0.47 µH, this product achieves a 16% higher rated current of 5.6 A and a 31% lower DC resistance of 22 mΩ, offering the highest standard* of electrical performance. This helps to reduce loss and improve efficiency for power supply circuits, enabling support for high-current applications within the same footprint as conventional models. Additionally, the inductor ensures high reliability with an upper operating temperature range limit of +150°C, thanks to a product design assuming use in high-temperature environments in automotive applications.
