Our NTC Thermistor Collection

Thermistors are thermally sensitive resistors whose electrical resistance changes predictively based on their body temperature. EI Sensor produces NTC and PTC thermistors in both standard and custom configurations.

NTC or negative-temperature-coefficient thermistors exhibit a large and predictable decrease in electrical resistance when subjected to an increase in body temperature.


EI Sensor uses its extensive product and industry knowledge to design, produce, and stock off-the-shelf NTC thermistors and related products that meet customer needs worldwide. We also work closely with customers to design and manufacture custom NTC thermistors for their specific applications.

NTC Thermistors from EI Sensor

Our dedicated team meets customer demand by stocking various NTC thermistors, including those with glass bodies, epoxy coated, surface mount MELF, and surface mount end-banded sensors.


EI Sensor and its distributors stock many thermistors, and probes to provide our customers with quick access to their needed products.


Contact us if you have questions about which stock products best fit your application. We will work closely with you to ensure you select the thermistor or other parts for long-lasting and accurate temperature sensing and control.


We are also pleased to support customers whose unique temperature measurement requirements need custom solutions.
