Dual-in-line resistor networks

30 May 2012 Passive Components

Vishay recently introduced a series of AEC-Q200-qualified, dual-in-line thin film resistor networks. The NOMCA series features low absolute TCR of ±25 ppm/°C, TCR tracking of 5 ppm/°C, tight ratio tolerances to ±0,05%, and long-term ratio stability of 0,05% after 1000 hours at +125°C. For improved ESD and moisture protection, the components are constructed with self-passivating tantalum nitride resistor film on a high-purity alumina or ceramic substrate.

Featuring a rugged, moulded 50 mil pitch construction, the resistor networks offer seven or eight isolated resistors of equal value in compact, narrow 14- or 16-pin SOIC packages. Each resistor offers a wide resistance range of 1 kΩ to 50 kΩ and a typical power rating of 100 mW.

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 1 kV at < 10 kΩ and 2 kV at > 10 kΩ. The devices feature very low noise of < -30 dB and voltage coefficients of < 0,1 ppm/V, and operate over a wide temperature range of -55°C to +125°C. They are compliant with RoHS Directive 2011/65/EU and halogen-free according to the IEC 61249-2-21 definition.
