TT-S Thermistors

CTS Electronic Components TT-S Thermistors feature fast response time, excellent stability, and reliability. These epoxy-coated Negative Temperature Coefficient (NTC) chip thermistors are available in custom sizes and wire configurations. The TT-S thermistors are similar to the TT3 series, with the main difference being resistance tolerance. These thermistors feature point-matched characteristics with a standard precision of ±1% at 25°C. The TT-S thermistors provide a cost-effective alternative to the interchangeable TT3 series thermistors, which are more precise but expensive. Typical applications include liquid or gas temperature control and monitoring, assembly into probes, automotive, industrial, computer and communications industry, HVAC, white goods, and military.
