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

• Resistor

material:

Tantalum

nitride,

self-passivating

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.

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

APPLICATIONS

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.

The QFX series resistor chips are designed for circuits

requiring high values with lower shunt capacitance for

higher frequency of operation.
