Monday, September 08, 2014: To meet the growing demand for AEC-Q200-qualified parts, Vishay Intertechnology, Inc has announced that its MC AT professional series of automotive thin film chip resistors is now AEC-Q200-qualified over its entire resistance range from 1 Ω to 1 MΩ. Designed to deliver stability under harsh environmental conditions in automotive and industrial applications, the Vishay Beyschlag devices offer high-temperature performance to +175 °C for 1,000 hours.

Offered in standard case sizes from 0402 to 1206, MC AT professional resistors feature tolerances down to ± 0.5 % and TCR down to ± 25 ppm/K. While competing devices typically offer power ratings to 250 mW at +70 °C ambient, the professional series resistors provide a high power rating of 400 mW at +85 °C in the 1206 case size for increased reliability.

With their excellent moisture and sulphur resistivity, operating voltages from 50 V to 200 V, and 1000 V ESD capability, the devices’ typical applications will include engine control units, climate control, braking systems, power supplies, lighting, and sensors in automotives; telecom base stations; and industrial and medical measurement equipment.

The MC AT professional resistors are approved to EN 140401-801. Suitable for processing on automatic SMD assembly systems, the devices are RoHS-compliant and compatible with lead (Pb)-free and tin/lead (Sn/Pb) reflow and vapor-phase soldering processes.
