Meisongbei electronics announces marketing of the new MSEC, meisongbei's smallest wire-wound inductor used for LCD TVs, plasma TVs, and other flat panel displays (FPDs).

In order to meet the demand for reduction of the mounting area of FPD's print circuit board by downsizing
choke coils, this product achieves a 6mm square case size with a rated current of 3.0A and Rdc of 47m
Ωs (at the inductance of 10μH).
Mass production is scheduled to begin in 2007 at the Meisongbei, one of the
company's overseas production sites. Together with the MSEC, made for LCD displays for notebook
PCs, the company plans to establish production capacity of 20 million units per month.

The FPD market is expanding everywhere all over the world, and the trend is toward higher performance at
lower prices. With this higher performance trend, the number of IC chips used in the FPD's input-output
circuits, image processing circuits, and information processing circuits, etc., is rising. Furthermore, power
supply circuits are increasingly placed for each IC chip, for more efficient supply of power toward the goal of
lower power consumption. However, input-output circuits, image processing circuits, and information
processing circuits use high-priced multilayer boards, and the expansion of circuit area due to the increase in
the number of power supply circuits has been a factor in pushing up FPD prices.
The DC-DC converter's main consistent part that also covers a large area is a choke coil, and naturally there
have been requests for downsizing choke coils as a way to reduce the mounting area of the print circuit board.
However, reducing the size of the wire-wound inductor used as the choke coil would sacrifice the rated current
and Rdc, which would degrade the efficiency of the DC-DC converter. As a result, it was believed that
shrinking the size while maintaining electrical characteristics was too difficult, and power inductors of 7mm to
10mm square range have been used.
Meisongbei Electronics tackled the problem by expanding on a variation of the MSEC series, which features a simple
sleeveless construction that strictly eliminates all wasted space, to realize a product that is more compact while
preserving the required performance choke coils for FPDs, with a rated current of 3.0A and Rdc of 47mΩ (at
the inductance of 10μH) in a 6mm square case size.
