The small BRHL2518 (2.5 x 1.8 mm, with a maximum height of 1.5 mm) wire-wound chip power inductors help enhance power conversion efficiency. They reduce volume by approximately 65% and enhances dc-dc converter efficiency by about 5%. The efficiency is achieved through the use of single-sided electrode terminals, optimum core design and the prevention of increased dc resistance through a smaller size. The use of alternative materials has also improved its high frequency characteristics. The power inductors feature low DCR ranges from 0.055 - 0.245 Ohms. Saturation current is 1,500 mA, and inductance is 2.2 µH. Operating temperature is specified at a range of -25º C to 105º C.
