THERMISTOR
HT thermistors are entirely new type of thermistor
for surface mounting (by reflow soldering) and were
acquired from advanced technology.
Our HT thermistors are adapted metal electrodes
packaged in a resin mold, unlike conventional chip
thermistors, and can offer 2% tolerance for a
resistance value at 25 C.
HT series (SMD Thermistor) is not only compact-
surface mounting type but also highly accurate and
reliable.
