Thick film automotive grade chip resistor - AC series, offer complete case sizes, high power rating and wide terminal for excellent heat dissipation. Thin film AT series features high precision, high reliability, low TCR, passed Anti-FOS test: ASTM-B-809-95, with robust design for high temperature and moisture resistance.

The ever increasing presence of electronics in the automotive environment requires a wide diversity of passive components possessing advanced product characteristics and superior reliability.

Not only are established systems like engine control, power steering, transmission, climate control, lighting, and ABS undergoing monumental changes, but relatively new systems, such as car-to-car communications, driver assistance, self-steering, and self-parking are experiencing similar transformations which call for a greater number of resistors and capacitors. Deeper integration within the automotive environment necessitates pushing the performance of passive components to the limit.

Yageo has made a new series of automotive-qualified d R Chip for use in current designs and as a precursor for future trends. The new R Chip are fully designed to meet the following criteria:

  • AEC-Q200 qualified
  • Full PPAP available
  • Capable of performing under the most demanding of conditions
  • Mass production under TS 19649 certification
  • For the majority of automotive applications, the workhorse solution has been the standard AC series of R Chip Thick Film technology, available in 0201 to 2512 case sizes.

High precision resistors working under humid conditions must meet unsurpassed reliability standards. R Chip Thin Film AT products from Yageo are the perfect choice for circuitry in power steering, instrument clusters, ECU, and ABS.
