The OTP-668D2 is a thermopile sensor in classic TO-46 housing. The sensor is composed of 116 elements of
thermocouple in series on a floating micro-membrane having an active area of diameter 700 μm. The thermopile sensor provides nearly Johnson-noise-limited performance, which can be calculated by its ohmic series resistance.
A thermistor with a lead connected to ground is also provided inside the TO package for ambient temperature reference.
TO-46 metal housing with IR absorber coating inside
Thermistor reference included
Low temperature coefficient of sensitivity
Ideally suited for ear thermometers, miniature pyrometer.
