Wire-Wound Power Inductor Offers Highest Rated Current for Size

Wed, 02/25/2009 - 10:46am
Taiyo Yuden (USA) Inc. announces the availability of its RL3225 series of compact, low profile, wire-wound chip inductors for switch-mode DC/DC converter applications in digital cameras, portable games, hard disk drives and other high-current-use devices. Measuring 3.2 mm × 2.5 mm with a 1.7 mm maximum height, the seven models in the BRL3225 series offer an impressive combination of high current and inductance and low DC resistance (RDC). Compact digital devices are seeing increased need for switch-mode DC/DC converters to maximize efficient use of battery power stretched to the limit by added end-device functionality. In response to this challenge, the company optimized the core shape and electrode structure of the conventional inductor design by means of a unique sleeveless square-core winding that eliminated all wasted space and thickened the lead wire inside the inductor to achieve the lowest possible DC resistance.
