Low Profile Flexible Film Temperature Sensors Ideal For Wearable Products

Murata is starting the mass production of a range of surface-mounted NTC temperature sensors that are packaged on a flexible printed circuit (FPC) film. With an FPC thickness of approximately 100um, they can be easily routed inside complex designs and tight spaces. Owing to their low heat capacity, the sensor’s thermal responsiveness is excellent.

Measuring 50.00 x 3.17 x 0.55mm the sensors are ideal for sensing the housing temperature of smartphones and tablets. They are also very suitable for use in wearable products for sensing body surface temperature.

The FTNT55XH103FA1A050 sensor can measure temperatures in the range of -40 to + 125 degrees C and has accuracy, at 25 degrees C of ±0.4 degrees C. Resistance at 25 degrees C is 10kohm ±1%. As smartphones and tablets have become more compact with even greater sophisticated functions the need to monitor the thermal design in space-constrained designs is more important.
