ACCURATE AXIAL TYPE THERMISTOR
IT THERMISTOR
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 Ϯ2% tolerance for a
resistance value of 25ЊC and Ϯ1% for B value.
IT thermistors are the most appropriate device for
accurate temperature control below 100ЊC.
