Chip size: 0.020 inches square
Resistance range: 10
Ω
to 510 kΩ
Resistor material: Nichrome
Quartz substrate: < 0.1 pF shunt capacitance
The QFN series nichrome on quartz resistor chips offer a
combination of nichrome stability, excellent frequency
response and small size.
The QFNs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The QFNs are 100 % electrically tested and
visually inspected to MIL-STD-883.
Power: 25 mW
APPLICATIONS
Vishay EFI QFN top-contact resistor chips are widely used in hybrid packages where space is limited. Designed with capacity to
handle substantial power loads, they also have the benefit of nichrome stability.
Recommended for hermetic environments where die is not exposed to moisture.
