Our newly developed
IT thermistors are axial
leaded diode type packaged in high-density resin
mold and featured strength against various operating
environments.
We offer
IT thermistor with
2% tolerance for a
resistance value of 25 C and
1% for B value.
IT thermistors are the most appropriate device for
accurate temperature control below 100 C.
