Taiyo Yuden’s BRL2515 (2.5 mm x 1.5 mm, with a maximum height of 1.2 mm) and BRFL2518 (2.5 mm x 1.8 mm, with a maximum height of 1.0 mm) wire-wound power inductors offer desirable DC bias characteristics in a thin, small size. With a rated saturation current of 1000 mA and inductance of 2.2 µH, the BRL2515 has an exceptional DC bias for a chip type coil, with a profile now 17 percent smaller than the existing BRL2518. The DC resistance of the BRL2515 ranges from 0.070 ? to 0.265 ? and the BRFL2518 offers a DCR range of 0.09 ? to 0.33 ?, while both featuring a low ACR. The operating temperature is specified at a range of -25ºC to 105ºC. Each of these low profile power inductors are designed for DC-DC converter applications in cell phones, smart phones, DSCs, portable music players and other equipment developed in response to the growing demanding for more compact and thinner mobile devices with more functionality.
