Abstract

A high temperature RFID tag (10,20) is described which has a survival temperature in the range of approximately -40°C to 300°C
and an operating temperature of approximately -20 °C to 200 °C.
The RFID tag comprises a housing (21) comprising a first thermally resistant material and having a base (24) and a top (22), and a circuit board substrate (26) which includes an IC circuit (28) and is disposed in a tag chamber (36), the substrate comprising a second thermally resistant material which is encapsulated in the housing.
The thermally resistant materials exhibit a deflection temperature in a range of 287 °C to 320 °C.
