TDK NTC Thermistor 10k Ohm 3988K, -55°C to 155°C

The TDK B57861S Series NTC Thermistor is a precision temperature measurement sensor designed for accuracy and reliability. Featuring a bead-type thermistor with bendable wire leads, it offers a short response time and high measuring accuracy, making it ideal for a wide range of monitoring and control applications.

This component is encapsulated in epoxy for durability and features PTFE-insulated leads. Two lead types are specified: one consisting of silver-plated nickel wire (AWG 30, 50mm length) and the other of silver-plated copper wire (19 x 0.07mm, AWG 28, 350mm length), providing flexibility for different installation requirements. The thermistor has a standard resistance of 10kohm at 25°C with a tight tolerance of ±1%, and a B-constant (B25/100) of 3988K, also with ±1% tolerance.
