TDK Corporation releases the L862 (B57862L)ย 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 ranging from -40 ยฐC to +155 ยฐC with a tolerance of ยฑ1% and ยฑ3%, respectively. At room temperature, their maximum power dissipation is 60 mW.ย
Both series are available with different rated resistances between 1ย kฮฉ and 100ย kฮฉ and different R/Tย characteristics (see tables below and on the next page). After 10,000ย h at +70ย ยฐC, the deviation of the resistance at room temperature R25ย is less than 3%.
The L862 sensor element, encapsulated in a black epoxy coating, is a mere 2.6 x 6.5 mm (in diameter and height) in size. It features insulated silver-plated nickel wire (AWG 30, with an outer diameter of 0.25 mm) as its leads.ย
The total length of the sensor including the wires is 50ย mm, with 6ย mm stripped. While the dissipation factorย ฮดthย of the sensorย is 1.4ย mW/K, its thermal cooling time constantย ฯcย is 14ย 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 (ร 0.4 mm) with a spacing of 2.5 mm. While the dissipation factor ฮดth of the sensor is 3 mW/K, its thermal cooling time constant ฯc is 9 s.
