• Manufacturer Part Number: 104AT-2
• Description: AT thermistor, 100KOhm
• Manufacturer: Semitec

CHIP TYPE THERMISTOR
14
Specifications
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.

Dimensions
Reflow soldering profile
*1 R
*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.
103 K T 2125T -
Do not expose the thermistors to high
soldering heat for more than specified time.
(260 C for not longer than 10s is
recommended)
Other resistance is available, please ask.
