Resistor-capacitor chip networks

TT electronics' BI Technologies SMT Division announced it has developed a series of resistor-capacitor chip networks that promises to replace up to 16 discrete components, saving 50 percent of PCB space. Designated the RC Series, the company said the thick film-on-ceramic chip networks are not susceptible to electrostatic discharge (ESD) and do not require diode protection.

"Many designs can use one RC network instead of 16 discrete components, and this reduced component count saves on PCB space, pick and place costs, as well as inventory and BOM costs. In addition, reducing the number of solder joints and traces on the PCB improves overall reliability," said Jim Rieley, sales director for BI Technologies' SMT Division. "The RC networks can be placed close to active devices, thus reducing PCB routing problems and minimizing inductance of long traces on the circuit boards."

The RC chip networks are suitable for a variety of circuits, including line terminations, EMI, keypad, ECG input, parallel port, serial port, SCART port, keyboard and mouse, and control and data line filters, in laptop and notebook computers, workstations, multimedia applications, automotive electronics, computer peripherals, cellular phones, and STB applications. The low-profile chip network is also suitable for PCMCIA applications.

The new devices are available as a single chip in 1206 size, as well as in five different circuit configurations in a 10-terminal 2512 array.

Power ratings for the RC Series are 63mW/resistor (250mW packaging rating). Resistance range for the networks is 20 ohms to 1 megaohm, with standard tolerance of 20 percent (10 percent and 5 percent tolerances also available). Capacitor dielectric is X7R with a tolerance of 20 percent. TCRs are 200ppm/C (optional TCRs at 100ppm/C are also available).

BI Technologies will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide. Samples are available immediately for engineering evaluation and customer prototypes.
