TH NTC Thermistors Amphenol Advanced Sensors TH Negative Temperature Coefficient (NTC) Thermistors are offered in a DO-35 style glass package with an axial solder-coated copper-steel wire. The glass body provides a hermetic seal, voltage insulation, and excellent stability. The diodes operate up to 250°C and are designed for accurate temperature measurement, control, and compensation. Amphenol TH NTC Thermistors resist corrosive atmospheres and harsh environments while providing tight tolerances and improved reliability. The TH series is ideal for automotive, telecom, and temperature sensing applications.
