Technical content

Description

  • Surface mount inductors, 4.0mm height, designed for higher speed switch mode applications requiring low voltage and high current
  • 155°C maximum total operating temperature
  • Design utilizes high temperature powder iron material with a non-organic binder to eliminate thermal aging
  • Inductance offering expanded for applications requiring higher inductance.
  • Inductance Range from 0.175 uH to 47.3 uH
  • Current Range from 39.0 to 2.4 Amps
  • Frequency Range 1kHz to 500kHz

Applications

  • Next generation microprocessors
  • High current DC-DC converters
  • VRM, multi-phase buck regulator
  • PC, Workstations, Routers
  • Telecom soft switches, Base Stations Environmental Data
  • Storage temperature range: -40°C to +155°C
  • Operating ambient temperature range:-40° C to +155°C (range is application specific)
  • Solder reflow temperature: +260°C max. for 10 seconds max. Packaging
  • Supplied in tape and reel packaging, 800 parts per reel Part Rated OCL (1) Irms (2) Isat (3) Isat (4) DCR (m Ω) Volts (5) Number Inductance nominal Amperes Amperes Amperes max. @ µSec (VµS) µH +/-20% µH (Typ.) 15% rolloff 30% rolloff 20°C (ref.) 1) Test Parameters: 100KHz, 1.0Vrms 2) Irms Amperes for approximately ∆T of 40°C above 85°C ambient 3) Isat Amperes Peak for approximately 15% rolloff (@20°C) 4) Isat Amperes Peak for approximately 30% rolloff (@20°C) 5) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS at operating frequency necessary to generate additional core loss which contributes to the 40°C temperature rise. De-rating of the Irms is required to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option). It is recommended that the temperature of the part not exceed 155°C under worst case operating conditions verified in the end application.
