TDK Corporation announces the L862 (B57862L) NTC thermistors with bendable wires and the L871 (B57871L) lead spacing NTC thermistors that can be used in a wide range of automotive and industrial applications. Both series are Pb-free and can measure temperatures between -40 °C and +155 °C with a tolerance of ±1% and ±3% respectively. At room temperature, their maximum power dissipation is 60 mW. Both series are available with different rated resistances between 1 kΩ and 100 kΩ and different R/T characteristics. After 10,000 h at +70 °C, the deviation of the resistance at room temperature R25 is less than 3%.
The sensor element of the L862 that is encapsulated with a black epoxy coating is just 2.6 x 6.5 mm (D x H) in size and has insulated leads of silver-plated nickel wire (AWG 30, Ø 0.25 mm). The total length of the sensor including the wires is 50 mm, with 6 mm stripped. While the dissipation factor δth of the sensor is 1.4 mW/K, its thermal cooling time constant τc is 14 s.
Also, the sensor element of the L871 is encapsulated with a black epoxy coating. It is just 2.8 x 6.0 mm (D x H) in size and has Cu-clad steel wires (Ø 0.4 mm) with a spacing of 2.5 mm. While the dissipation factor δth of the sensor is 3 mW/K, its thermal cooling time constant τc is 9 s.
Main applications
