Development of Next Generation Coiled Power Inductor by Toko
Toko inc. a leading Japanese developer and manufacturer of electronics parts that developed the world’s first intermediate frequency transformer (IFT) for transistor radios back in 1955, today made an announcement on development of next-generation coiled power inductor with measly size of 2.5×2.0×1.2mm. The newly power inductor has been targeted to be implemented in such personal electronic application as cell phones, smart phones and digital cameras to name a few. The new product combines the coil and the core into a single unit resulting in reduced audible noise which is normally associated with coils. The new coiled power is approximately 80% smaller in element volume size than company’s previous model which was 4mm square. The new coiled power was designed based on patented process in using proprietary materials, structures and methods. The development of this product was respond to increasing demand for smaller, thinner products using low-resistance coils and highly dense flat power lines as well as metallic magnetic materials capable of resisting magnetic saturation plus it can be used in direct currents. The new coiled power inductor will go in mass production by beginning of April 2010.
