Wire-Wound Inductors Handle High Current In EIA 1210 Form Factor January 14, 2009
The BRL3225 series wire-wound chip inductors measure 3.2 mm x 2.5 mm with a 1.7 mm maximum height and offer a combination of high current and inductance with low dc resistance. For example, the BRL3225T-1R0M handles 2.4A at 1-µH inductance while exhibiting 0.043 Ohms of dc resistance. The series lays claim to specifying the highest current rating in a 1210-size device. To achieve this feat, the components employ an optimized core shape and electrode structure plus a unique sleeveless square-core winding that eliminates wasted space. Also, a thicker lead wire inside the inductor reportedly enables the lowest possible dc resistance. Sample pricing is $0.20 each. TAIYO YUDEN INC., Schaumburg, IL. (800) 348-2496.
