MC AT resistors

Vishay Intertechnology is now offering its MC AT series of professional thin-film chip resistors in the 0402, 0603, 0805, and 1206 case sizes. The manufacturer also released a new precision version of the series with lower TCR and tolerances.

The MC AT professional and precision resistors are designed to deliver stable performance in high-temperature and humidity operation. The professional series devices feature high-temperature performance to 175C for 1,000 hours and high power ratings of 400mW at an 85C ambient temperature.

The MC AT also features a superior high pulse load capability compared to typical resistors in the same case sizes. For example, the 1206-size MC AT device features ESD robustness to 2000V (human body model). With excellent resistivity to moisture, verified under the severe conditions of 85C and 85 percent RH for 1,000 hours, all MC AT devices are optimized to provide high reliability in harsh environments.

The precision series offers low TCRs down to 15ppm/K and tight tolerances of 0.1 percent, while both new series feature an extended resistance range down to 47.

In addition to AEC-Q200 compliance, the MC AT series is CECC approved. CECC approval ensures that MC AT resistors meet a set of demanding and sophisticated short-term and long-term performance requirements as defined by EN 140401-801.
