Power Inductors Designed for DC-DC Converter ApplicationsTaiyo Yuden’s BRL2515 (2.5 x 1.5 mm, with a maximum height of 1.2 mm) and BRFL2518 (2.5 x 1.8 mm, with a maximum height of 1.0 mm) wire-wound power inductors offer industry-leading DC bias characteristics in a thinner, smaller size.

With a rated saturation current of 1,000 mA and inductance of 2.2 µH, the BRL2515 has an impressive DC bias for a chip type coil, with a profile now 17% smaller than the existing BRL2518. The DC resistance of the BRL2515 ranges from 0.07 ? to 0.265 ? and the BRFL2518 offers a DCR range of 0.09 ohms to 0.33 ohms, while both feature a low ACR. Operating temperature is specified at a range of -25 to 105ºC.

Each of these new space saving, low profile power inductors are designed for DC-DC converter applications in equipment developed in response to the growing demand for more compact and thinner mobile devices with more functionality.
