DC-DC converter suits compact digital equipment
Taiyo Yuden
BRHL2518 wire-wound chip power inductor
Suitable for use in mobile devices, such as digital cameras, Taiyo Yuden's BRHL2518 wire-wound chip power inductor is a compact DC-DC converter that enhances power-conversion efficiency.
Measuring 2.5 x 1.8mm with a maximum height of 1.5mm, the BRHL2518 reduces volume by approximately 65 per cent and enhances DC-DC converter efficiency by about five per cent when compared to Taiyo Yuden's CBC3225T2R2M Series, which measured 3.2 x 2.5 x 2.5mm.
The BR Series' efficiency is achieved through use of single-sided electrode terminals, new 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 1,500mA and inductance is 2.2uH.
Operating temperature is specified at a range of -25C to +105C.
It 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 USD0.20 (GBP0.12) per unit.
