Wire-wound Power Inductor Offers Highest Rated Current For Size

摘要

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 x 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 resis- tance (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 elec-trode 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.
