New SMD power inductors are constructed from low-loss ferrite core

Update: November 26, 2021

New Yorker Electronics now offers the new Sumida CDB38D38 line of high-efficiency power inductors from Sumida Group. Similar to other types in the CDB series, this new surface mount Inductor is magnetically shielded with low DCR tolerance and high efficiency. The series is intended for low ferrite core loss.

The new CDB38D38NP-R065MC offers an inductance of 0.065% ±20% and a saturation current of 24.5A max, while the CDB38D38NP-R10PC provides an inductance of 0.1 ±25% and a saturation current of 14.5A max. Both versions offer a typical DCR of 0.32mOhm at 20 degrees.

The new series will generally be employed in multi-phase and Vcore regulators and server and desktop VRMs, CPUs and GPUs. Other usages will cover ASIC, high power density and data networking density, graphics cards, and battery power systems.
