Wound Power Inductor Line with 2.8mm Height Devices

Taiyo Yuden 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.

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.
