Recent Developments in Fixed Resistors

The commoner types of resistor used in electronic apparatus are discussed in terms of recent developments. In most cases developments have been largely progressive improvements without fundamental changes in the component. Some of the more interesting of recently developed types are also considered, these being metal films and metal oxide films and combinations. Their potentialities are outlined. The paper concludes with some account of resistors that are in the process of development and may be available soon. Improvement and development in pyrolytic carbon resistors is foreseen and wider availability and use of metal and metal oxide films are predicted.
