SMD Power Inductor: CDB80D62

April 24th 2019

SUMIDA has developed a high current inductor CDB80D62, like other CDB series, CDB80D62 is in magnetic shielded surface mount structure, constructed by low loss ferrite core, with low DCR tolerance and high efficiency.

Key Features:

  • Ferrite core construction
  • Magnetically shielded
  • L×W×H: 22.2×8.2×6.6mm Max.
  • Operating temperature range: -40℃~+125℃ (including coil’s self temperature rise)



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); Graphics cards and battery power systems

Parts List:

(A) ※3
20℃ 125℃
CDB80D62NP-R23MC 0.23 ± 20% 0.47 ± 15% 76.00


※1 Measuring frequency inductance at 1MHz.

※2 Saturation current: this indicates the value of D.C. current when the inductance becomes 20% lower than it’s initial value.
※3 Temperature rise current: the actual value of D.C. current when temperature of coils becomes △T=40℃ (Ta=20℃).
