SURFACE MOUNT TYPE THERMISTOR
HT
Part number
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.
