North Star Sensors leaded NTC thermistors are available in a variety of R/T curves, R25 values, temperature tolerances, and lead configurations. Leaded NTC thermistors are noted for their fast time response and ruggedness. They are the one of the most cost-effective and versatile temperature sensor available for the temperature range of -50 °C to 150 °C.
Leaded NTC thermistors are available with insulated or uninsulated leads, a range of coatings and encapsulations, and a wide spread of R25 values from 100 Ω to 100,000 Ω. Epoxy coatings and epoxy / polymer tube constructions are common because they balance environmental protection with response time.
If you need help choosing the right family, North Star Sensors can help you balance dimensions, lead style, tolerance, and curve selection for your application.

Uninsulated Leads
NTC thermistors with uninsulated leads are one of the industry's most typical and most versatile NTC thermistor configurations. They are suitable for mounting on PC boards or potting inside temperature housings. Their small size, low cost, ruggedness, and sensitivity to changes in temperature make them the ideal choice for applications in the range of -50 °C to +150 °C.
Here are a few examples of uninsulated leaded NTC thermistors:
| Part Number | 25 °C Ω | Curve | Electrical Tolerance | Lead | Thermistor Coating | Max OD |
|---|---|---|---|---|---|---|
| 1AE103R44T1A | 10,000 Ω | 44 | 0.1 °C from 0 °C to 70 °C |

Insulated Leads
NTC thermistors with insulated leads are an excellent option for simplifying subsequent assembly steps using NTC thermistors as components. This can lower the assembly costs while also reducing potential points of failure such as unwanted electrical contact to a housing. Additionally, using insulated leads may increase the assembly's overall ruggedness and ability to withstand various environmental conditions.
