CTN

Vishay Electro-Films

Nichrome 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 total: 10 Ω to 1 MΩ

• Ratio tolerances to: 0.1 %

• Resistor material: Nichrome

• 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.
