QFX www.vishay.com Vishay Electro-Films Thin Film, Top-Contact Megohm Resistor FEATURES • Wire bondable • Chip size: 0.050 inches square • Case: 0505 • Resistance range: 500 k to 10 M • Quartz substrate: < 0.1 pF shunt capacitance 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. • Resistor material: self-passivating Tantalum nitride, • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS The QFX series resistor chips are designed for circuits requiring high values with lower shunt capacitance for higher frequency of operation.
