TT Electronics' IRC Division Introduces Series Of Wire Bondable Chip Resistors

Corpus Christi, TX -- Providing design engineers with tantalum nitride based resistors on silicon suited for hybrid applications, TT electronics IRC Advanced Film Division has introduced a series of wire bondable chip resistors. Designated the WBC Series, the resistors feature IRC's self-passivating tantalum nitride thin film technology on silicon substrates.

According to Dr. Debasis Roy, Director of IRC Advanced Film Division's Thin Film Business Unit, the WBC Series resistors have a resistance range that is unmatched by any competitor. "We have extended the resistance values for these resistors to range from 10W to 400KW," he said. "The extended range allows for better surge protection in higher power applications, such as hybrid circuits." The tantalum nitride film provides precision tolerance and exceptional TCR tracking, Dr. Roy continued. Absolute tolerance ranges are down to ±0.1%, with absolute TCRs to ±25ppm/°C.

The wire bondable chip resistors are available in 0202 and 0303 chip sizes. The 0303 center-tapped chips can be used in feedback circuits of amplifiers, where ratio matching, high power and close tracking between two resistors is critical.
