CMF0402102F3450FB High Precision SMD NTC Thermistor With Excellent Welding Performance For Surface Mounting
0402 Series NTC Patch thermistor
NTC thermistor is a kind of manganese, cobalt, nickel metal oxides as raw material sintering of ceramic semiconductor thermal crystals,
high sensitivity to temperature change, the zero power resistance decreases, with the body temperature rise with the temperature
resistance exponential decline, temperature coefficient as high as (3~6% / ℃), small temperature changes can cause great resistance
change. According to the R-T resistance value temperature curve of the thermistor, the precise resistance value of each temperature
point can be calculated. In the circuit, the digital temperature correspondence can be realized through the resistance value, which is
used for temperature measurement and control.
