TDK Corporation introduces two new NTC thermistors designed for precise temperature measurement in automotive and industrial environments. The L862 and L871 series operate across a temperature range of -40°C to +155°C, with power dissipation rated at 60 mW at room temperature.The L862 features a 2.6 x 6.5 mm sensor element with silver-plated nickel wire leads (AWG 30, 0.25 mm diameter). This model achieves ±1% tolerance with a dissipation factor of 1.4 mW/K and a thermal cooling time constant of 14 seconds. The 50 mm leads include 6 mm stripped ends for installation flexibility.
The L871 incorporates Cu-clad steel wires (0.4 mm diameter) with 2.5 mm lead spacing. Its 2.8 x 6.0 mm sensor delivers ±3% tolerance, with a 3 mW/K dissipation factor and 9-second thermal cooling time constant. Both models maintain resistance stability, showing less than 3% deviation in R25 after 10,000 hours at +70°C.
Available in resistance ratings from 1 kΩ to 100 kΩ, these Pb-free thermistors serve applications including battery packs, power banks, and energy storage systems.
