Quad precision thin film surface-mount resistor networks in
5mm x 5mm QFN package
Vishay has introduced the new quad precision thin film
surface-mount resistor networks that feature a 20-pin 5-mm
x 5-mm quad flat no-lead package with a 0.65-mm pitch and
low 1-mm profile.
These devices offer 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 suitable for differential amplifier applications
in industrial, telecommunication, military, medical, test
and measurement instrumentation and equipment.
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.
The devices offer 100 Ohms per resistor to 500 kOhms per
package, power ratings of 50 mW at + 70 °C per resistor,
very low noise of < - 30 dB, voltage coefficients of
0.1 ppm/V.
Operating temperature range: - 55 °C to +125 °C
Availability: Samples and production quantities of the
QFN series are available now
