Vishay Intertechnology has introduced the industry's first quad precision thin film surface-mount resistor networks to feature a 20-pin 5-mm by 5-mm quad flat no-lead package with a 0.65-mm pitch and low 1-mm profile. The new package format of the QFN series saves 30 % to 60 % on PC board space compared to traditional 20-lead SOIC packages.

The devices released today feature precision ratio tolerances to ± 0.05 % and stable film and performance characteristics of 500 ppm at + 70 °C for 2,000 hours. The QFN resistor networks offer low TCR to ± 25 ppm/°C and tight TCR tracking to ± 5 ppm. These specifications make the devices ideal for differential amplifier applications in industrial, telecommunication, military, medical, and test and measurement instrumentation and equipment.

Due to the devices’ custom circuit capability, resistance values can be different for each resistor in the QFN networks, and range from 100 Ω per resistor to 500 kΩ per package. The devices offer power ratings of 50 mW at + 70 °C per resistor, very low noise of < - 30 dB, voltage coefficients of 0.1 ppm/V, and a temperature range of − 55 °C to +125 °C.

The QFN devices are qualified to Moisture Sensitivity Level 1 per J-STD-020. Offering lead (Pb)-free terminations, the resistor networks are compliant with RoHS Directive 2002/95/EC and flame-resistant in accordance to UL 94 V-0. Custom configurations of the devices are available.
