Vishay Electro-Films
Thin Film, Center-Tapped Resistors
FEATURES
• Wire bondable
Product may not
be to scale
• Center tap feature
• Chip size: 0.030 inches square
• Resistance range RT: 10 Ω to 36 kΩ
• Alumina substrate, low shunt capacitance: < 0.2 pF
• Resistor material: Tantalum nitride
• Moisture resistant
The CTT series resistor chips offer a combination of low
shunt capacitance and excellent stability. The CTT offers the
designer flexibility in use as either a single value resistor or
as two resistor with a center tap feature.
The CTTs six bonding pads allows the user increased layout
flexibility. The CTTs tantalum nitride resistor material offers
excellent resistance to high moisture environments.

The CTTs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The CTTs are 100 % electrically tested and
visually inspected to MIL-STD-883.

APPLICATIONS
The CTT center-tapped resistor chips are used mainly in
feedback circuits of amplifiers where ratio matching,
tracking, low shunt capacitance and better frequency
response are necessary.
