OTP-N538U, THERMOPILE

THERMOPILE Thermopile Sensor OTP-N538U Revision Date: 2018/01/08 (Rev.05) OTP- N538U The OTP-N538U 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 545 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
