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
Ω.
