DESCRIPTION
These thermistors have a negative temperature coefficient.
The device consists of a chip with two tin-plated copper
leads. It is grey lacquered and not insulated. These
thermistors are very accurate (鹵0.5 擄C) over a trajectory
from 25
擄
C to 85
擄
C.
PACKAGING
The thermistors are packed in cardboard boxes, each box
contains 500 units.
MARKING
Grey lacquered body.
MOUNTING
By soldering in any position.
