Inductors and Chokes

CoEv Magnetics, a business unit of Tyco Electronics, has introduced a new SMT series of surface-mount inductors and chokes. These power magnetic devices are designed for a wide range of switch-mode power supply (SMPS) applications. They are used to suppress and filter ac ripple current in the dc output circuit, and they can also be used for energy storage and common mode noise attenuation.

The SMT devices feature toroidal cores in a convenient surface-mount package. The unique header design provides quick and efficient installation by incorporating a new wire-clamping feature that lowers the time required in the manufacturing process. CoEv Magnetics now offers nine series of SMPS inductors, coupled inductors, and common mode chokes which help minimize circuit board real estate requirements in power supplies, telecommunications equipment, computers, and cable modems. They are also suitable for 150-kHz and 260-kHz National Semiconductor SimpleSwitcher™ applications.
