ΔR/R
The CTA series resistor chips combine the best tolerances,
stability and low shunt capacitance. The CTA offers the
designer flexibility in use as either a single value resistor or
as two resistors with a center tap feature. The CTAs six
bonding pads allows the user increased layout flexibility. The
CTAs are manufactured using Vishay Electro-Films (EFI)
sophisticated thin film equipment and manufacturing
technology. The CTAs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
The CTA 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.
Recommended for hermetic environments where chip is not
exposed to moisture.
For lower values, the resistance of the six bonding-pad
configurations can vary, depending on the method of
measurement used. Vishay EFI measures low-value
resistors by the four-wire Kelvin technique. The measuring
method is illustrated in the diagram to the right.
