A single-channel silicon-based thermopile with very high output for its small 0.6mm x 0.6mm active area in a small TO-18 package. Delivers a fast 18ms time constant in Argon encapsulation gas and even faster with Neon gas at 9ms.Delivers a very low Temperature Coefficient of Responsivity of -0.04%/°C.
Excellent for non-contact temperature and gas analysis.
High output, small active area, fast time constant in a small package that has a higher cost.
