CTN www.vishay.com Vishay Electro-Films Nichrome Thin Film, Center Tapped Resistor Divider Network FEATURES • • • • • • • • • Product may not be to scale 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 please see www.vishay.com/doc?99912 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.
