Type 3150 Series
This is the ultimate in lightweight, low
profile skeleton 4mm surface mount
potentiometers. Offered in easy, top or
underside adjustment, with a plus
slot that is ideal for automatic top
adjustment. At a weight of 0.2 grams
and a profile height that is only 1.5mm
above the board, it is a natural
choice for new generation hand held
equipments. The trimmer is a mere
4mm and is a well proven and popular
package supplied on standard 12mm
tape for automatic placement, and
reflow soldering systems. The central
hole is filled with resin to improve
ease of pick and placement.
