Thin-Film Resistors Find Hybrid Applications

For chip-resistor designs, high reliability can be successfully gained by utilizing a thin-film-on-Aluminum-Nitride design. The thin-film components from State of the Art have a maximum power rating that is five times higher than conventional chip resistors. The designs come with two termination styles. The first—ground isolation—features a solderable solid bottom pad and two solderable top-surface terminals. The second style—ground connect—boasts a single wraparound. This wraparound connects the resistor to a solderable bottom pad. It has a single top surface pad for the other connection.

These high-power resistors are available in values from 10 and 1000 ohms. They have tolerances of +/− 0.1% and a temperature coefficient of resistance to 50 ppm. A variety of case sizes are available from 1206 (0.125 × 0.65 in.) to 3838 (0.375 × 0.375 in.).

The compact, lightweight, high-power designs are ideal for high-current-pulse applications like power supplies. They also are suitable as microwave terminations. In fact, their thin-film design makes them ideal for applications in which current noise is a consideration. As an added benefit, Aluminum Nitride is a low-toxic alternative for use in programs that require environmentally friendly products.
