TDK offers compact inductors with enhanced performance capabilities to address smartphone power circuit demands

TDK Corporation has developed the new TFM201208BLE series of inductors optimized for space-constrained smartphone power circuits. These are available in 0.24, 0.33 and 0.47 µH versions.

Each supplied in a 2.0 (L) x 1.2 (W) x 0.8 mm (H) form factor, the inductors in this latest TDK series feature significantly better electrical properties than the previous TFM201208BLD products - in terms of their current and resistance levels. A 10% higher rated current of 5.5 A (Isat), 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, 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 (more info).
