NTC Thermistors, Low Thermal Gradient Lug Sensors
Note
(1)
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
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
MOUNTING
The device is suitable for screwing e.g. on a metal surface
through means of an M3 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.
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
