Ticer Technologies Embedded Resistor Calculator
This downloadable resistor calculator is a tool used by printed board designers to select sheet resistivity while considering resistor size, shape and power handling capability. The tool can help the designer select one or more of the available TCR ohms per square sheet resistance values to capture and eliminate more surface mounted resistors. It also has an input for etch factors, which allows designers and fabricators to better predict the final tolerance of the finished resistor.  The calculator is available in both metric and imperial (inch) formats.
