EPCOS / TDK T850 NTC Thermistors

EPCOS / TDK T850 NTC Thermistors are designed for surface temperature measurement and offer 10kΩ rated resistance with 1% or 2% tolerance. These sensors combine high humidity resistance with fast response time and offer a high dielectric strength of 2500VAC for 60s. The modules are suitable for harsh environments in temperatures ranging from -40°C to +150°C and are waterproof for up to 500 hours. The miniature package has an aluminum oxide ceramic surface and dimensions of 10mm x 3mm x 3mm. Additional features include a wider sensing surface area, phosphor bronze electrodes, and mechanical robustness. EPCOS / TDK T850 NTC Thermistors can be attached to a metal heatsink or bars as well as directly to a chassis.
