, thickness 1.5 mm, in still air at T
amb
= +25 °C
FEATURES
• Easy mounting with screw
• Rugged construction
• UL recognized, file E148885
(UL category XGPU2)
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
APPLICATIONS
• Temperature measurement, sensing and control
• Suitable for surface temperature applications, especially
when a good electrical insulation and a good thermal
contact with the chassis is required
DESCRIPTION
The thermistors are made of NTC ceramic material reflow
soldered between two solid tinned copper wires or low
thermal conducting 0.5 mm solid tinned nickel wires and
potted in the head of passivated aluminum (size M4).
PACKAGING
The thermistors are packed in cardboard boxes; the
smallest packaging quantity is 100 units.
DESIGN-IN SUPPORT

MARKING
4 digits marking indicating resistance value and tolerance 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
or in a threaded screw hole. Applied torque shall not exceed
1.2 Nm. Leads to be soldered or crimped.
