CTQ Vishay Electro-Films CHIP RESISTORS Thin Film Center-Tapped Resistors FEATURES Product may not be to scale * Wire bondable * Center tap feature * Chip size: 0.030 inches square * Resistance range total: 10 to 1 M The CTQ series resistor chips offer a wide resistance range with lower shunt capacitance than can be offered with the silicon based resistors but only at a lower power level. The CTQ offers the designer flexibility in use as either a single value resistor or as two resistor with a center tap feature. The CTQs six bonding pads allows the user increased layout flexibility. The CTQs are manufactured using Vishay Electro-Films (EFI) sophisticated thin film equipment and manufacturing technology. The CTQs are 100 % electrically tested and visually inspected to MIL-STD-883. * Resistor material: Tantalum nitride, self-passivating * Moisture resistant * Quartz substrate * Low shunt capacitance < 0.1 pF I V RA RB V I V APPLICATIONS The CTQ center-tapped resistor chips are used mainly in feedback circuits of amplifiers where ratio matching, low shunt capacitance and tracking between two resistors is critical. For low values, the resistance of the six bonding pad configuration can vary, depending on the method of measurement used. Vishay EFI measures low-value resistors by the four-wire kelvin technique.
