TDK Corporation has introduced the L862 (B57862L) and L871 (B57871L) NTC thermistors, designed for a variety of applications, including electric vehicle (EV) battery packs.
These thermistors offer reliable temperature measurement within a range of -40° to +155° C, with tolerances of ±1% and ±3%, respectively. With rated resistances between 1 and 100 kΩ and multiple R/T characteristics, the components are Pb-free and engineered to meet automotive and industrial demands.
Both thermistor series are compact and durable. The L862, encapsulated in black epoxy, measures just 2.6 x 6.5 mm (D x H) and features silver-plated nickel wire leads for insulated, bendable connections. Its thermal cooling time constant is 14 seconds, with a 1.4 mW/K dissipation factor.
Additionally, the L871 is slightly larger at 2.8 x 6.0 mm (D x H) and includes Cu-clad steel wires with a 2.5 mm spacing. This model offers a faster thermal cooling time constant of 9 seconds and a dissipation factor of 3 mW/K.
Key features like short response times, high measurement accuracy, and customizable tolerances make these thermistors suitable for EV battery packs, power banks, energy storage systems, and drones. Their reliable performance ensures precise thermal monitoring, which is essential for optimizing battery safety and efficiency.
