0805 Ceramic 470 OHM 50% Surface Mount thermistor 0603 32V SMD PTC Thermistor
Surface Mount CPTC Ceramic PTC Thermistor 0603 470 OHM 50% Limit Temperature Sensors
I Description Of The 0805 Ceramic SMD PTC Thermistors
Ampfort Superior series SMD PTC thermistors employ a more homogenous ceramic material, which enables them to exhibit excellent performance in reliability tests and be reflow and wave-soldered at temperatures of up to 280°C. Because of these properties, they have been qualified based on AEC-Q200 Rev-C and satisfy the rigorous requirements for use in automotive electronics applications that involve frequent and rapid temperature changes.
