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 m Ω than conventional products have been attained.* These parameters are the best in the industry for inductors of this size.** 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 TFM201208BLE series offer the much-needed value to smartphone OEMs delivering the necessary high current and low resistance.
TDK’s overall TFM series also has a wide variety of inductors for automotive applications, including products with 40 V voltage ratings for use in EV powertrains. TDK is constantly expanding its array of products, enabling a wider range of power circuit needs.
