وصف
ال PTC linear thermistor produced by DTTTEK is an axial lead glass package. Its resistance value increases linearly with the increase of temperature, and the linearity is good. Compared with the thermistor synthesized by PTC polymer ceramics, it does not need to take linear compensation measures to simplify the circuit design. And it has good resistance consistency, strong interchangeability, and standardized appearance and specifications.
