WBC series of wire bondable chip resistors feature 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 resistors have an unmatched resistance range. “We have extended the resistance values for these resistors to range from 10 to 400KW. The extended range allows for better surge protection in higher power applications, such as hybrid circuits.” 

 Absolute tolerance ranges are down to ±0.1%, with absolute TCRs to ±25ppm/°C.
 
The resistor film provides stability over time and temperature, for increased power dissipation.

The chip resistors are available in 0202 and 0303 chip sizes.  The 0303 center-tapped chips can be used in feedback circuits of amplifiers.
