Notes
1. For values of nominal resistance value and tolerance at
intermediate temperatures; see resistance values tables.
2. Response time in silicone oil MS 200/50. This is the time needed
for the sensor to reach 63.2% of the total temperature difference
when subjected to a temperature change from 25

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 (±0.5 °C) over a trajectory
from 25
°
C to 85
°
C.
PACKAGING
The thermistors are packed in cardboard boxes, each box
contains 500 units.
MARKING
Grey lacquered body.
MOUNTING
By soldering in any position.
