Bb sensors ts ntc series radial precision temperature sensors bb sensors ts ntc 103a a high accuracy precision temperature sensor with a zero power resistance of 10k and a beta2585 value of 3976k the sensor is suitable for applications where more expensive platinum resistors are generally used and due to the excellent 05 tolerances on both the zero power resistance and beta value the sensor can be used without the need for temperature calibration and may be replaced without re adj
