Pulse introduces the PG0255NL series of low profile, surface mount (SMT) flat coil inductors. With a saturation current rating up to 30 A and a heating current rating up to 38 A, these inductors are designed for the multiphase voltage regulator modules (VRMs) supporting the increasing current needs of Vcore power in PC notebooks and other DC/DC applications. The four inductors in the series, the PG0255.201NL, PG0255.401NL, PG0255.601NL, and PG0255.222NL, have inductance values from 0.2 to 2.2 µH. The range of inductance values gives VRM designers the ability to tailor their designs for faster transient response with the lower inductance values or lower switching losses using lower switching frequencies with the higher inductance values. The inductors' low direct current resistance (DCR) of 0.55 to 7.0 mOhms and low alternating current loss result in lower copper losses, providing high efficiency in DC/DC power conversion applications. The flat coil inductor windings are made of rectangular copper (flat wire) wound helically, similar to a spring. Pulse , Guildford, Surrey GU2 7RE, UK. www.pulseeng.com.
