      The OTP-667F4P is a thermopile sensor in classic TO-5 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 element, with a lead connected to ground, is also provided inside the TO package for ambient temperature reference.
    • TO-5 metal housing with IR absorber coating inside
    • Thermistor reference included
    • Low temperature coefficient of sensitivity
    • Ideally suited for ear thermometers, miniature pyrometer.
