FL Temperature Sensor Preliminary Jan 2013

Low Profile
Temperature
Sensor
Low profile sensor for applications in confined
spaces.
The FL temperature sensor is a small NTC chip sensor enclosed in a flexible PCB that measures surface
temperature. It is designed to meet the volume, cost, and delivery expectations of Original Equipment
Manufacturers (OEMs).
Applications

lifetime.
•
Low profile applications.
•
Low profile – 0.5 mm maximum thickness.
•
Flexible PCB design.
•
Electrical connection by soldering or edge
connection.
•
Suitable for temperature measurement in
rechargeable battery packs.
•
Low mass NTC thermistor for fast ti me
response.
•
Alternative RvT curves available.
•
Custom Flexible PCB lengths available.
