Vishay Intertechnology, Inc. introduced a new series of AEC-Q200-qualified, dual-in-line thin film resistor networks. The NOMCA series features low absolute TCR of ± 25ppm/°C, TCR tracking of 5 ppm/°C, tight ratio tolerances to ± 0.05%, and excellent long-term ratio stability of 0.05% after 1,000 hours at + 125°C. For improved ESD and moisture protection, the resistor networks are constructed with self-passivating tantalum nitride resistor film on a high-purity alumina or ceramic substrate.
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 (0.150in.) 14- or 16-pin SOIC packages, in accordance with JEDEC MS-012 variations AB and AC. Each resistor offers a wide resistance range of 1kΩ to 50kΩ and a typical power rating of 100mW.
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. Samples of the NOMCA resistor networks are available now.
