Oxidized silicon substrate for good power dissipation
The CTN series is a center tapped nichrome resistor chip
providing excellent stability at 250 mW power levels. The
CTN offers the designer flexibility in use as either a single
value resistor or as two resistors with a center tap feature.
The CTNs six bonding pads allows the user increased layout
flexibility.
The CTNs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The CTNs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
The CTN center-tapped resistor chips are used mainly in feedback circuits of amplifiers where ratio matching, high power and
tracking between two resistors is critical.
Recommended for Hermetic environment where die is not exposed to moisture.
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.
