APPLICATIONS
• Temperature measurement, sensing and control in
industrial, consumer and telecom applications. For
on-board sensing or accurate remote sensing
DESCRIPTION
These thermistors are made of NTC ceramic material. The
device consists of a chip with two tinned nickel leads. The
parts are coated and color band marked. Tape and reel
versions available on request.
Thermal time constant
τ
PACKAGING
The thermistors are packed in cardboard boxes; the
smallest packing quantity is 500 units.
Notes
(1)
Response time in silicone oil MS200/50. 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. Thermal time constant by cooling from
electrically pre-heated body
(2)
Valid for all types with the exception of the

MARKING
The thermistors are marked with color bands on a grey
epoxy base coating; see Dimensions and “Electrical Data
and Ordering Information”.
MOUNTING
By soldering in any position. Not intended for potting.
