Wirewound Power Inductors suit flat panel displays.
Press Release Summary:
Measuring 6 x 6 x 2.8 mm, NR6028 series adds design flexibility for dc-dc converter choke-coil applications in flat panel displays (FPDs). Sleeveless, square-core winding eliminates wasted space, and thickened lead wire inside inductor achieves lowest possible DC resistance. Series is comprised of 13 models with dc resistance values from 0.013-0.6 ohms, inductance values from 0.9-100 µH, and current ratings from 0.62-6.6 A.

New Taiyo Yuden Power Inductor Improves Current Rating 36 Per Cent
Taiyo Yuden Expands Wire-Wound Power Inductor Line with 2.8 mm Height Devices; 10µH Model Offers 36% Higher Rated Current
Available now, new 6 x 6mm NR6028 series adds even more design flexibility to company's selection of inductors for DC-DC converter choke-coil applications in flat panel displays
SCHAUMBURG, Ill. - July 17, 2008 - TAIYO YUDEN (U.S.A.) INC. announces the NR6028 series of 6mm x 6mm x 2.8 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 13 models in the NR6028 series offer an excellent selection of low DC resistance (0.013 - 0.6 Ohms), high inductance (0.9 - 100 µH), high current ratings (0.62 - 6.6 A) and improved performance versus previous company models. The NR6028-100M device, for example, provides 36% higher rated current at 10µH inductance. The NR6028 series broadens the company's line of 6 x 6 mm wire-wound power inductors which now includes an even greater selection of maximum height dimensions offering unprecedented design flexibility for a wide range of market needs. These parts include: 1.2 mm (NR6012 series); 2.0 mm (NR6020 series); 2.8 mm (NR6028 series) and 4.5 mm (NR6045 series) height devices.
Compared to earlier models, the latest FPDs include many more IC chips in the I/O, image processing and information processing circuits. Each IC chip typically includes its own power supply circuit to more efficiently use power and to lower overall consumption as much as possible. Such ICs require costly multi-layer boards that have grown larger due to more power supply circuits, a factor that has also driven up FPD prices. This has resulted in higher 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 device size very difficult. TAIYO YUDEN responded to this 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 NR series inductors that successfully eliminated all wasted space and thickened the lead wire inside the inductor to achieve the lowest possible DC resistance.
