The CTR series is a center-tapped resistor chip combining
excellent stability with 250 mW power levels. The CTR offers
the designer flexibility in use as either a single value resistor
as two resistors with a center tap feature. The CTR’s six
bonding pads allows the user increased layout flexibility.

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

APPLICATIONS
Vishay EFI CTR center-tapped resistor chips are used
mainly in feedback circuits of amplifiers where ratio
matching, high power and tracking between two resistors is
critical.
For low 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 method
illustrated above is critical for resistors of less than 100 .
