Power Inductor Allows for more Compact and Energy Efficient Mobile Devices

Thu, 03/17/2011 - 7:56am
Ideal for use in mobile devices, the 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 to 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.
