Power Inductor Allows More Compact and Energy Efficient Mobile Devices

Ideal for use in mobile devices, Taiyo Yuden's BRHL2518 (2.5 x 1.8mm, with a maximum height of 1.5mm) wire-wound chip power inductors help to realize a more compact DC-DC converter, and to enhance power conversion efficiency.

Compared to Taiyo Yuden's CBC3225T2R2M Series (3.2mm x 2.5mm x 2.5mm), the BRHL2518 reduces volume by approximately 65% and enhances DC-DC converter efficiency by about 5%. The BR Series' 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.

The BRHL2518 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.

Taiyo Yuden's BRHL2518 meets today's demands for a reduction in size and an improvement in energy efficiency of many digital devices, including mobile devices, compact digital equipment, digital cameras and portable music players.

The BRHL2518 sample price is $0.20/unit.
