The CTQ series resistor chips offer a wide resistance range with
lower shunt capacitance than can be offered with the silicon
based resistors but only at a lower power level.
The CTQ offers the designer flexibility in use as either a
single value resistor or as two resistor with a center tap
feature. The CTQs six bonding pads allows the user
increased layout flexibility.
The CTQs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The CTQs are 100 % electrically tested and
visually inspected to MIL-STD-883.

APPLICATIONS
The CTQ center-tapped resistor chips are used mainly in feedback circuits of amplifiers where ratio matching, low shunt
capacitance and tracking between two resistors is critical.
For low values, the resistance of the six bonding pad configuration can vary, depending on the method of measurement used.
Vishay EFI measures low-value resistors by the four-wire kelvin technique.
