TFM-BLE Series Power Inductors

TDK's TFM-BLE series of inductors are available in 0.24 µH, 0.33 µH, and 0.47 µH versions. The inductors in this TDK series feature significantly better electrical properties than the previous TFM-BLD products (with regards to their current and resistance levels). A 10% higher rated current of 5.5 A (I_SAT), plus a 22% lower DC resistance of 25 mΩ than conventional products have been attained. The major boost in performance has been achieved through TDK’s innovative metallic magnetic material technology and structural design.

SoCs with elevated arithmetic throughput will be required as smartphone performance further progresses, and the accompanying passive components must exhibit higher current characteristics. In addition, the integration of ever more functionality into smartphone designs is increasing the number of power circuits involved. Consequently, the inductors employed must have low resistance and contribute minimal losses to extend battery life. The TFM-BLE series offer the much-needed value to smartphone OEMs delivering the necessary high current and low resistance.
