SMD type chip
Chip thermistors are specially processed, highly
reliable thermistors.
They can be face-bonded to act as thermal
compensators for ICs and they are manufactured
in sizes down to 1 square mm, they can also be
used to detect temperature with relatively small
time constants.
Precautions
Do not expose the thermistors to high
soldering heat for more than specified time.
(260 C for not longer than 10s is
recommended)

: Rated zero-power resistance value at 25 C.
*2 B value : determined by rated zero-power resistance at 25 C and 85 C.
*3 Time when thermistor temperature reaches 63.2% of the temperature difference. The value is measured in the air.
Other resistance is available, please ask.
