SMD Power Inductor: CDB38D38

October 15th 2021

High current inductor CDB38D38, like other types in the CDB series, they are in magnetic shielded surface mount structure, and constructed by low loss ferrite core, with low DCR tolerance and high efficiency.

Key Features:

  • Ferrite core construction
  • Magnetically shielded
  • Operating temperature range: -40℃~+125℃ (including coil’s self temperature rise)

 

Applications:

Multi-phase and Vcore regulators; Voltage Regulator Modules (VRMs), such as server and desktop, Central Processing Unit(CPU); Graphics Processing Unit (GPU); Application Specific Integrated Circuit(ASIC); high power density, data networking density, graphics cards and battery power systems

※1 Measuring frequency inductance at 1MHz.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 20% lower than its initial value.
※3 The temperature rise: the actual value of DC current when the temperature rise is △t=40℃ (Ta=20℃).
