■
Small size, light weight and good stability |
|
■
Metal cermet resistor
body, 3-layer electrode, Special technology, higher
reliability, have good solderability |
|
■
Large-scale reduction of actual placement area,
suitable for high density placement, Actual
placement area efficiency is greatly enhanced by
2-4times that of chip resistors |
