Taiyo Yuden (U.S.A.), Inc.’s CKP3216 series of 1206 case size multilayer chip inductors offer one of the industry's lowest profiles for DC/DC converter choke coil applications in portable electronic device power circuits. With a maximum height of 0.9 mm, CKP3216 series devices provide a lower profile than typical surrounding ICs, thus facilitating the design of thinner, higher-performance, multifunction cell phones, digital still cameras, digital video cameras and other battery-powered ultra-portable electronic equipment. Offering current ratings from 0.7 to 1.1 A and 4.7 to 1.0 µH, respectively, CKP3216 series chip inductors are now available in mass production quantities. A proprietary new internal-electrode printing process enabled Taiyo Yuden to double the thickness of the internal conductor compared to the company's previous-generation devices, resulting in lower DC resistance (RDC). Another material science-derived improvement was the prevention of inductance drop during the application of high current, an essential requirement in ultra-portable applications. New additions to the CKP3216 series, now under development, are expected to result in further performance gains in 1206 case size.
