CTT Vishay Electro-Films CHIP RESISTORS Thin Film, Center-Tapped Resistors FEATURES * Wire bondable * Center tap feature Product may not be to scale * Chip size: 0.030 inches square * Resistance range RT: 10 to 36 k The CTT series resistor chips offer a combination of low shunt capacitance and excellent stability. The CTT offers the designer flexibility in use as either a single value resistor or as two resistor with a center tap feature. * Alumina substrate, low shunt capacitance: < 0.2 pF * Resistor material: Tantalum nitride * Moisture resistant The CTTs six bonding pads allows the user increased layout flexibility. The CTTs tantalum nitride resistor material offers excellent resistance to high moisture environments. The CTTs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The CTTs are 100 % electrically tested and visually inspected to MIL-STD-883. I I RA I RB APPLICATIONS The CTT center-tapped resistor chips are used mainly in feedback circuits of amplifiers where ratio matching, tracking, low shunt capacitance and better frequency response are necessary. Vishay EFI measures low-value resistors by the four-wire kelvin technique.
