This article covers improved fabrication techniques, design rules, and fundamental understanding of PTF resistor technology. No other resistor technology, available now or in development, can match PTF's cost, resistance range, size reduction potential, and tolerances.
Passive components represent a significant portion of the total components in portable electronics. They can take up half the board surface area, account for 25% of the solder joints, and cost more than the circuit board itself. Motorola's Embedded Passives program strategy is to replace surface mount capacitors, inductors, and resistors with embedded counterparts that are equally reliable, free up ...
