B57861 NTC Thermistors for Temperature Measurement

TDK B57861 NTC Thermistors for Temperature Measurement provide a short response time and a temperature curve from -40°C to +155°C. The B57861 thermistors are equipped with a JST connector and feature epoxy encapsulation as well as PTFE-insulated leads of silver-plated CU wire. These TDK probe assemblies are ideal for temperature measurement applications.
