Wire-Wound Inductors feature 0.8-8.5 A current ratings.
Press Release Summary:
Including 14 models, NR6045T series of 6 x 6 x 4.5 mm wire-wound power inductors offer 0.014-0.5 W) dc resistance and 1.0-100 µH inductance. Model NR6045T-100M delivers 3.0 A at 10 µH in 6 x 6 mm form factor. Sleeveless, square-core winding eliminates all wasted space and thickens lead wire inside inductor. Units are suited for dc-dc converter choke coil applications in LCD/plasma TVs and other flat panel displays.
Original Press Release:
Taiyo Yuden's New Wire-Wound Inductor Achieves Industry's Highest Rated Current for Its Size
SCHAUMBURG, IL-November 12, 2007-TAIYO YUDEN (U.S.A.) INC. announces the NR6045T series of 6 x 6 x 4.5 mm height (max) wire-wound power inductors for DC-DC converter choke coil applications in LCD/plasma TVs and other flat panel displays (FPDs). The 14 models in the NR6045T series (see product table below) offer an excellent selection of low DC resistance (0.014 - 0.5W), high inductance (1.0 - 100 µH) and high current ratings (0.8 - 8.5A). The NR6045T-100M device, for example, offers the industry's highest rated current (3.0A @ 10µH) in the 6 x 6 mm form factor. With the equivalent performance of larger 7 to 10 mm square devices, the 26% to 64% smaller footprint, respectively, of NR6045T series devices facilitates more compact DC-DC converters and thinner-profile product designs.
Due to the aggressive price/performance quest of the expanding global FPD market, greatly increased numbers of IC chips are now required for the I/O, image processing and information processing circuits of flat panel displays. Power supply circuits are likewise increasingly used for each IC chip to more efficiently use power and lower overall consumption as much as possible. These circuits, however, require costly multi-layer boards that have grown in size due to the increase in the number of power supply circuits, a factor that has also driven up FPD prices. This has resulted in a corresponding demand for choke coils-the main component in DC-DC converters-with higher current capacity, lower DC resistance (RDC) and smaller physical size. Boosting current capability, however, requires increasing the size of the core and thickening the windings inside the inductor, both of which make reducing the device's size very difficult.
TAIYO YUDEN responded to this design challenge by improving the round drum/sleeve core technology used by conventional inductor designs. A unique sleeveless, square-core winding was developed for use by the NR series inductors that successfully eliminated all wasted space and thickened the lead wire inside the inductor to achieve the lowest possible DC resistance.
