Press Release Summary:
Providing self-passivating tantalum nitride thin film technology on silicon substrates, wire bondable WBC Series features absolute tolerance ranges down to ±0.1%, with absolute TCRs to ±25 ppm/°C. Resistance range to 400 kΩ allows for surge protection in high power applications. Units are available in 0202 and 0303 chip sizes. Center-tapped 0303 chips can be used in feedback circuits of amplifiers, where ratio matching and close tracking between 2 resistors is critical.
Original Press Release:
IRC'S Wire Bondable Chip Resistors Extend Resistance Range To 400Kohm
CORPUS CHRISTI, TX (November 1, 2005) - Providing design engineers with tantalum nitride based resistors on silicon suited for the most demanding 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 10 ohms to 400 Kohms," 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.
IRC's self-passivating tantalum nitride resistor film provides excellent stability over time and temperature, giving the WBC resistors exceptional power dissipation.
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.
As with all IRC products, devices outside these specifications can be produced to meet specific customer requirements. Pricing for the WBC Series resistors typically starts at $1.00 in quantities of 1,000 pieces.
