Thin Film, Top-Contact Megohm Resistor
Product may not be to scale
The QFX series, tantulum nitride on quartz resistor chips
combine high resistance with low shunt capacitance. These
offer one of the best combinations of small size, frequency
response and high value available.
The QFXs are manufactured using Vishay Electro-Films (EFI)
sophisticated thin film equipment and manufacturing
technology. The QFXs are 100 % electrically tested and
visually inspected to MIL-STD-883, method 2032 class H
or K.
