Catalogs Display Latest Magnetics Wares

A number of magnetic component suppliers have released catalogs updating their offerings for power and other applications. Premier Magnetics has published a new 140-page catalog detailing the company's line of magnetics devices for networking, communications and power supply applications. The catalog provides a comprehensive collection of datasheets covering an extensive selection of specialized transformers, filters, chokes and inductors.

In addition, the catalog features details on the company’s low wattage dc-dc converters. The entire collection also is available as individual .pdf datasheets at www.premiermag.com.

Among the power components included in the catalog are switch-mode power supply magnetics, linear transformers, toroidal transformers and dc-dc converter modules.

From Cooper Electronics Technology, a unit of Cooper Bussmann, the Coiltronics brand catalog offers 120 pages of information updated with the newest inductors and transformers. A series of application notes has been added to make selection of products easier. Improvements in the catalog are meant to provide a more technical focus. In addition, information is included on improving reliability of power inductors in high temperature designs, PoE power magnetic options and trends, and switching regulator inductor selection.

In addition to detailed applications and specifications for each product line, the guide has an easy-to-use custom magnetics design form with step-by-step guidelines to determine the proper size and efficiency of the SMT component needed for a specific electronic application. Almost 1000 different part numbers are listed for every conceivable power requirement and space configuration in the design of electronics, including 12 additional values for the HC8 Series of power inductors.
