The thermal gradient is the difference per °C between the true
temperature of the surface to be sensed and the temperature
measured by the sensor
FEATURES
• Low thermal gradient due to the use of nickel
conductor and low profile closed ring tongue
• AEC-Q200 qualified (grade 1)
• UL recognized, file E148885
(UL category XGPU2)
• Mounting: assembly screw mounting
• Material categorization: for definitions of
compliance please see www.vishay.com/doc?99912
APPLICATIONS
Thermistors used for accurate surface temperature sensing
and control in:
• Computer equipment
• Power electronics, heat-sink temperature control
• Consumer appliances
• Industrial equipment
• Automotive equipment
DESCRIPTION
Vishay thermistor chip NTC with epoxy coating and middle
buffer layer mounted in a tin plated copper ring lug with
PEEK insulated leads AWG#30 (Ø 0.25 mm),
mono-stranded silver-plated nickel.
MOUNTING
• The device is suitable for screwing e.g. on a metal surface
through means of an M3 or M3.5 screw
• The connections are suitable for soldering on a PCB or for
connector insertion
• The sensor is not suitable for being in permanent contact
with water or liquids
• Other applicable screw hole sizes are available, for
example M4 or American Stud #8
• AWG#28 or AWG#26 wires available on request
• Consult Vishay for other cable length, cable section,
screw sizes, insulation, connector crimping or other
features
