Revision: 10-Oct-03
89
FEATURES
Excellent accuracy between 25
C and 85
C
High stability over a long life.
APPLICATIONS
Temperature sensing and control.
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.
QUICK REFERENCE DATA
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
C in air to
85
C in oil.
