APPLICATIONS
Suitable for many applications, especially when a good
insulation and/or a good thermal contact with the chassis is
required.
Thermistor with negative temperature coefficient and two
solid tinned copper leads.
The device is mounted in the head of aluminium screws
size M4.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 100 units.
MARKING
The last 4 digits of the catalog number are printed on the stud
in accordance with the information in Electrical Data and
Ordering Information Table.
MOUNTING
By means of a washer and M4 nut supplied with the device.
Applied torque shall not exceed 1.2 Nm. Leads to be
soldered.
