Wound-Chip Inductors Sport Low Profile

New low-profile wound-chip inductors have been designed specifically for use in dc/dc converter choke-coil applications. The NR inductor series provides up to 30% higher rated current than conventional inductors of equal size. With a 4 mm x 4 mm footprint, the NR4010, NR4012 and NR4018 measure 1 mm high, 1.2 mm high, and 1.8 mm high, respectively. To increase rated current, the company has developed a unique ferrite-resin compound. When applied to the exterior of the wound chip inductor, the compound allows more space for the internal conductor, minimizes heat generation and improves dc inductance characteristics. NR inductors also boast improved shock resistance. When mounted on pc boards, they are said to have excellent damage-free durability, even when dropped from a 6' height. Pricing starts at $0.22 each.
