Taiyo Yuden’s BRHL2518 (2.5 mm x 1.8 mm, with a maximum height of 1.5 mm) wire-wound chip power inductors are presented as helping to realize a more compact DC/DC converter, and to enhance power conversion efficiency. Compared to the company’s CBC3225T2R2M Series (3.2mm x 2.5mm x 2.5mm), the BRHL2518 reduces volume by approximately 65 percent and enhances DC-DC converter efficiency by about 5 percent. Its efficiency is achieved through the use of single-sided electrode terminals, optimum core design and the prevention of increased DC resistance through a reduced size. The incorporation of alternative materials in the BRHL2518 has also improved its high frequency characteristics. This inductor features 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 -25ºC to 105ºC. The BRHL2518 is suitable for mobile devices, compact digital equipment, digital cameras and portable music players.
