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.
Wire bondable
Center tap feature
Chip size: 0.030" x 0.030"
Case: 0303
Resistance range total: 10  to 1 M
Ratio tolerances to: 0.1 %
Resistor material: Nichrome
Oxidized silicon substrate for good power dissipation
Material categorization: For definitions of compliance

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.
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, method 2032 class H
or K.
