TTI is now stocking thick film/thin film automotive-grade chip resistors from Yageo in Europe. Thick film AC series resistors offer complete case sizes from 0201 up to 2512, high power rating and wide terminal for excellent heat dissipation. Thin film AT series devices feature high precision, high reliability, low TCR, passed Anti-FOS test: ASTM-B-809-95, with robust design for high temperature and moisture resistance. They are suitable for use in power steering, instrument clusters, ECU, and ABS.
The AC series and AT series components are based on Yageo’s automotive-qualified d R chip and designed to meet the following criteria: AEC-Q200 qualified, full PPAP available, capable of performing under the most demanding of conditions, as well as mass production under TS 19649 certification.
