Compact Power Inductors offer optimized DC bias characteristics.
August 25, 2010 -
With respective DC resistance ranges of 0.070-0.265 W and 0.09-0.33 W, BRL2515 measures 2.5 x 1.5 mm with max height of 1.2 mm and BRFL2518 measures 2.5 x 1.8 mm, with max height of 1.0 mm. Both RoHS-compliant, wire-wound power inductors operate from -25 to +105°C and are designed for DC-DC converter applications in mobile devices such as cell phones, smart phones, DSCs, and portable music players. Saturation current ratings range from 650 to 1,500 ma (BRL2515) or 1,200 mA (BRFL2518).

New Compact, Low Profile Power Inductors from Taiyo Yuden
TAIYO YUDEN UNVEILS TWO NEW COMPACT, LOW PROFILE POWER INDUCTOR FOR MOBILE DEVICES
Schaumburg, IL - Taiyo Yuden's new BRL2515 (2.5 x 1.5mm, with a maximum height of 1.2mm) and BRFL2518 (2.5 x 1.8mm, with a maximum height of 1.0mm) wire-wound power inductors offer industry-leading DC bias characteristics in a thinner, smaller size.
With a rated saturation current of 1000 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 0.070 W to 0.265 W and the BRFL2518 offers a DCR range of 0.09 ohms to 0.33 ohms, while both featuring a low ACR. Operating temperature is specified at a range of -25ºC to 105ºC.
Each of these new space saving, 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.
Both the BRL2515 and BRFL2518 inductors are 100% RoHS-compliant. The BRL2515 and the BRFL2518 sample price is $0.20/unit.
