World's smallest multilayer power inductor

TDK Kasei Takashi, CEO of TDK Co., Ltd. has developed the world's smallest multilayer power inductor with a size L of 1.0×W: 0.5×H: 0.7 (mm).

Based on the dimensions of the previous product L:1.6×W:0.8×H:0.8 (mm), this product is further pursuing miniaturization, with the volume and package area reduced by approximately 60%. The product will be installed in the power circuit of mobile devices such as smartphones and tablet terminals, and mass production will begin in July 2013.

In addition, the use of low-loss ferrite as a magnetic material, which is unique in the structure design of the company and material technology, realizes characteristics that can be used in a few hundred mA power supply circuit in a small size of 1005.

In recent years, mobile devices have been increasingly used in environments with high power consumption due to continuous use of large-capacity high-speed communications. At the same time, due to the multifunctionality, the power supply circuit has a multilayer structure, and the number of power inductors is increasing. For this reason, it is necessary to solve the problem of battery life and space saving of the power circuit. While saving space, the product also meets the need to increase power efficiency.

In the previous product series 2520 (L: 2.5 × W: 2.0mm), 2016 (L: 2.0 × W: 1.6mm), 2012 (L: 2.0 × W: 1.2mm), 1608 (L: 1.6 × W: 0.8mm) Based on the various dimensions of the product, plus the products of this time, we will provide a more extensive product lineup in the future.

The main application of smart phones, tablet terminals, digital cameras and other power supply modules, and other main features and advantages through a small and thin to save the package area can be used under hundreds of mA power circuit
