      The OTP-678D4 is a thermopile sensor in classic TO-46 housing.

      The sensor is composed of 112 elements of thermocouple in series on a floating micro-membrane having an active area of 0.5mm2.

      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 temperature reference included
    • Low temperature coefficient of sensitivity
    • Ideally suited for ear thermometers, miniature pyrometer.
