This improved structure allows for a 2% to 3% increase in Vcore voltage regulator efficiency, a 35% to 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 +130° Celsius. The use of ferrite core material makes these inductors immune to thermal aging, increasing system reliability.
The PA2080NL series is 10.5mm long x 7.5mm wide x 8.9mm high maximum with inductance ranging from 140nnH to 220nH, a DCR of 0.49 milliOhm ±4%, and up to 80Apk. The PA1894NL series is 10.0mm long x 9.0mm wide x 10.0mm high maximum with inductance ranging from 185nH to 335nH, a DCR of 0.64 milliOhm ±4%, and up to 72Apk. 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.
