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)
• Material categorization:
