Vishay / BC Components NTCLE317 will sense the exact temperature within ±0.5°C, unlike other components with more thermally conductive wires like copper. This can be characterized by a gradient measurement of less than 10mK/K. The small size of the bead provides for a response time in air of <3s. The PEEK insulator of the lead wire has good adhesion with epoxy (unlike Teflon, for example) and will improve the behavior of the components in high humidity conditions (85°C/85% RH). Because the NTCLE317 is also 100% compliant to AEC-Q200 with a maximal use temperature of 150°C, it is ideal for automotive applications (thermally and electrically).
