Ferrite-based inductors raise
reliability
Power bead inductors use a single-turn conductor with a ferrite core instead of a multiturn conductor wound on a powdered iron toroid core.
Focus EDL has released what it says is the industry's first series of through-hole power bead inductors for desktop architectures Produced by Pulse, the PA1894NL and PA2080NL series use a single-turn conductor with a ferrite core instead of a multiturn conductor wound on a powdered iron toroid core

DSL filter put to alarming use
A novel filter has been designed specifically to allow monitored intruder alarm systems to connect to a DSL activated line.
This improved structure allows for a 2-3% increase in core voltage regulator efficiency, a 35-55% reduction in inductor footprint, and enables the tightest direct current resistance (DCR) tolerance available in the industry at +/-4%.
The operating temperature is -40 to +130C.
The use of ferrite core material makes these inductors immune to thermal aging, increasing system reliability.
The PA2080NL series has maximum dimensions of 10.5 x 7.5 x 8.9mm with inductance ranging from 140 to 220nH, a DCR of 0.49mohm +/-4%, and handles peak currents up to 80A.
The PA1894NL series measures 10.0 x 9.0 x 10.0mm with inductance ranging from 185 to 335nH, a DCR of 0.64mohm +/-4%, and up to 72A.
The footprint of the inductor series is designed to fit the pin-pitch of existing toroid solutions for easy test and verification.
They are used in power supplies for microprocessors (Vcore power circuit) in desktop, gaming, server and workstation applications.
