NTC Type MS
Thermometrics Epoxy-
Coated Thermistor
Description
Epoxy-coated point-matched disc thermistors
with 0.01 in (0.254 mm) nickel PTFE insulated lead-
wires.
Features
• Low cost, solid state temperature sensor
• High sensitivity to changes in temperature
• Suitable for temperature measurement,
control and compensation
• Standard resistance tolerances down to ±2%
• Excellent mechanical strength
• Wide operating temperature range: -58°F to
300°F (-50°C to 150°C)
• Suitable for PCB and probe mountings
• Available in a wide range of material systems
• Overall lengths from 0.71 in to 3.07 in (18 mm
to 78 mm)
