Vishay Intertechnology Inc. has unleashed a series of AEC-Q200-qualified, dual-in-line thin film resistor networks. The NOMCA series offers low absolute TCR of 25ppm/C, TCR tracking of 5ppm/C, tight ratio tolerances to 0.05 percent and long-term ratio stability of 0.05 percent after 1,000 hours at 125C, boasted the company.

The resistor networks are constructed with self-passivating tantalum nitride resistor film on a high-purity alumina or ceramic substrate, delivering improved ESD and moisture protection, noted Vishay. Featuring a rugged, molded 50 mil pitch construction, the NOMCA thin film resistor networks offer 7 or 8 isolated resistors of equal value in compact, narrow 14- or 16-pin SOIC packages, in accordance with JEDEC MS-012 variations AB and AC. Each resistor offers a wide resistance range of 1-50k? and a typical power rating of 100mW.

According to Vishay, the integrated construction of NOMCA resistor networks allows for higher precision over discrete SMT chips, making the devices ideal for precision voltage dividers, op amps and battery management applications. Typical end products will include automotive, telecommunications, industrial, process control and medical equipment.

Per AEC-Q200, the resistor networks are rated for ESD to 1kV at less than 10k? and 2kV at more than 10k?. The devices feature very low noise of less than -30dB and voltage coefficients of Samples of the NOMCA resistor networks are available now. Production quantities will be available in May, with lead times of eight to 10 weeks for standard orders.
