Features

!

1) A high durability protective film has been developed newly as a counter measure against static electricity.

2) The clip connector for the FFC specifications has been developed newly using an original technology thereby making
it possible to achieve even smaller size.

3) A newly developed 144-bits IC levels the strobe partition and reduces the noise level.

4) One rank resistance value of 1500Ω±3% eliminates the inconvenience of rank selection.
