Vishay Electro-Films

Thin Film, Center-Tapped Resistor

FEATURES

• Wire bondable

Product may not

be to scale

• Center tap feature

• Tight ratio tolerances to: 0.1 %

• Chip size: 0.030 inches square

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.

• Resistance range total: 25 Ω to 35 kΩ

• Alumina substrate, low shunt capacitance: < 0.2 pF

• Resistor material nichrome

• Excellent stability: 0.025 % maximum ΔR/R

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.

R_A

R_B

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.
