Power Bead Inductors Improve Efficiency

Pulse introduces seven series of power bead inductors, providing the ability to optimize performance across a range of applications, frequencies and load requirements. These efficient, off-the-shelf power beads are suitable for multi-phase buck regulator applications. Their low direct current resistance (DCR) minimizes inductor conduction losses, their low-loss ferrite cores minimize inductor switching losses and their small footprint enables more board layout flexibility. These power bead inductors consist of 2 through-hole (THT) and 5 surface-mount (SMT) power bead series. The THT beads are typically used in power supplies for desktop computing, while SMT versions are used in notebook computing, servers, graphics cards and point-of-load (PoL) applications.
