CHIP RESISTORS
FEATURES
· Chip size: 0.020 inches square
Product may not be to scale
· Resistance range: 10 to 510k · Resistor material: nichrome · Quartz substrate: < 0.1pF shunt capacitance · Power: 25mW
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) s o p h i s t i c a t e d thin film equipment and manufacturing technology. The QFNs are 100% electrically tested and visually inspected to MIL-STD-883.
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.
