Vishay Electro-Films

Thin Film, Center-Tapped Resistor Divider Network

FEATURES

• Wire bondable

• Center tap feature

• Tight ratio tolerances to: 0.1 %

• Chip size: 0.030" x 0.030"

• Case: 0303

Product may not be to scale

• Resistance range total: 25  to 35 k

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, method 2032 class H

or K.

• Alumina substrate, low shunt capacitance: < 0.2 pF

• Resistor material nichrome

• Excellent stability: 0.025 % maximum R/R

• Material categorization: For definitions of compliance

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.

R_A

R_B

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.
