December 4, 2021  Stephen Law

SUMIDA GROUP CDB38D38 line of high-efficiency, surface mount power inductors are magnetically shielded with low DCR tolerance and high efficiency.  Product Series is designed for low ferrite core loss. CDB38D38NP-R065MC device has an inductance of 0.065% ±20% and a saturation current of 24.5A max, while the CDB38D38NP-R10PC has an inductance of 0.1 ±25% and a saturation current of 14.5A max.  Both versions have a typical DCR of 0.32mOhm at 20°. Devices will be commonly be used in multi-phase and Vcore regulators and server and desktop voltage regulator modules (VRMs), CPUs and GPUs.
