(*1) Our investigation of choke coils with the metal-composite core structure as of February 7, 2012
February 7, 2012 Osaka, Japan–Industrial Devices Company, Panasonic Corporation has succeeded in commercializing the “Power choke coil” featuring compact size, large current, and low loss with the lowest DC resistance value in the industry (*1). Newly developed power choke coils are suitable for DC/DC converter circuits used in smart phones, tablet PC, HDDs etc.

As smart phones and HDDs used in tablet PC, game machines have become larger memory as well as faster, power supplies to be used have been required to have larger capacity and faster transient-response when starting up from standby mode. To meet for these requests, the power supply circuits has been becoming faster switching frequency and larger current. Besides, with the increasing multi-layer of HDD-disks, power supply circuits have been required to be thinner. Accordingly, choke coils to be used in DC/DC converter circuits have been required to be thinner, smaller, as well as larger current, and lower loss. To meet the market demand, Industrial Devices Company, Panasonic Corporation has developed power choke coils featuring smallest, largest current, lowest loss with the lowest DC resistance in the industry, and will commence mass-production.
