CEATEC2013-23a e A4 (210mm×297mm)
Thin Film Power Inductors TFM2016 & TFM2520 Series
New Product
CEATEC2013-23a
Small, low-profile power inductors for high currents/low DC resistance
The TFM series of compact power inductors is mainly designed for use in power supply circuits of
smartphones, tablets, and other mobile devices.
The lineup comprises 2.0 x 1.6mm (2016 size) and 2.5 x 2.0mm (2520 size) products with a maximum
thickness of 1.0mm. The use of proprietary pattern forming technology developed by TDK, together with a
material featuring improved magnetic saturation characteristics, results in current handling ratings on the
order of several amperes, regardless of the small footprint and low height of the inductors.
Features
• Proprietary TDK pattern forming technique realizes low profile and low DC resistance.
• Superior DC superposition characteristics compared to conventional ferrite type power inductors
• Closed magnetic circuit design reduces leakage flux.
Major Applications
• Power supply circuitry in smartphones, tablet devices, and similar
Low DC resistance and good DC superposition characteristics contribute to improved power conversion
efficiency of power supply circuits.
