NTC thermistor T850

SMD

Overview
TDK's T850 SMT NTC sensor (B57850T0103*) is designed for accurate surface temperature measurement in demanding industrial environments. It provides high moisture resistance and fast thermal response through excellent thermal coupling to the measurement surface. Rated for operation from -40 °C to +150 °C, the sensor is waterproof for up to 500 hours and features an aluminum oxide ceramic surface offering a dielectric strength of 2500 V AC for 60 s. The lead- and halogen-free construction includes phosphor bronze electrodes and allows contacting by piston soldering, laser soldering, micro-resistance welding or TIG welding.
