THT and SMT power bead inductors

13 May 2009 Passive Components

Pulse recently introduced seven new series of power bead inductors, giving designers the ability to optimise performance across a broad range of applications, frequencies and load requirements.

The highly efficient, off-the-shelf power beads are a suitable solution for multiphase buck regulator applications. Their low direct current resistance (DCR) minimises inductor conduction losses, their low-loss ferrite cores minimise inductor switching losses, and their small footprint enables board layout flexibility. These new power bead inductors consist of two through-hole (THT) and five 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.

The new inductor series - PA1682.XXXNL, PA2083.XXXNL, PA2509.XXXNL, PA2202.XXXNL and PA2607.XXXNL SMT models and PA2150.XXXNL and PA2125.XXXNL THT models – offer a wide range of inductances and current ratings.

All Pulse power beads are RoHS compliant and meet UL94 V0 standards, and can support a peak reflow soldering temperature of 260°C. SMT inductors come in tape-and-reel packaging, while the THT inductors are packaged in trays.
