产品信息
The OTP-868D2 L3.0 is a thermopile sensor with optical lens.
The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of 0.9 mm2.
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.
