Hello,
I am electronics engineer of CUB from Taiwan.
I am looking for a electronic parts of NTC Thermistors, which specification is showed as below
Resistance at 25 : 2500 ohm
B-value : 5500 K
Does your company have this kind of electronics part?
If you have the NTC Thermistors or any alternative parts, please contact with me, thank you very much.
Best Regards,
CUB ELECPARTS INC.

How to calculate B constant ? (2008-08-05)
How to calculate B constant ?
Administrator ( 2008-08-05)
B constant is an index of the thermal sensitivity expressed by the formula:
B=（LnR1-LnR2）/（1/T1-1/T2)
RT1--Resistance in ohms at temperature T1
RT2--Resistance in ohms at temperature T2
T1=2731.5k +( T1℃), T2=2731.5k+ (T2℃)

What is NTC Thermistor?

NTC: Negative Temperature Coefficient
Thermistor: Thermally Sensitive Resistor
Thermistor is a semiconducting ceramic resistor produced by sintering the materials at high temperature and made mainly from metal oxide. NTC thermistors are resistors with large negative temperature coefficient. Change in resistance of the NTC thermistors can be brought about either externally by a change in ambient temperature or internally by self-heating resulting from a current flowing through the device. At certain measure power, its resistance reduce rapidly while the temperature getting increase. Taking advantage of this characteristic, it can achieve the detecting and controlling temperature purpose.
