  • Carbon composition, cracked carbon, metal film and metal oxide resistors

    Publication Year: 1974, Page(s):188 - 194
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1647 KB)

    Typical manufacturing processes, nominal parameters and the major advantages and disadvantages of carbon composition, metal oxide, carbon film and low value nickel film resistors are discussed. The structure of these resistors is shown by photomicrographs, in some cases coupled with X-ray probe analysis. View full abstract»

  • Realization of a double-ladder operational amplifier network by CA-association

    Publication Year: 1974, Page(s):195 - 199

    The transfer function of a double-ladder network constrained by an infinite gain operational amplifier is realized by associating it with a C parameter (CA-association). A low-pass network can always be realized by such an association; whereas, in the realization of a transfer function with finite transmission zeros, there are some constraints. View full abstract»

  • Production testing of capacitors

    Publication Year: 1974, Page(s):201 - 208

    The progress of automatic testing of capacitors is summarized and an indication given of future trends. The most promising method of testing is to make contact to a large number simultaneously and to carry out a sequence of tests by automatic switching under computer control. The best place for this testing is while the components are orientated in manufacturing jigs. At the present time the speed... View full abstract»

  • Connector standards and BS 9000

    Publication Year: 1974, Page(s):209 - 215

    A brief history of early standards and war-time connectors is followed by an account of the work of the post-war component standardization committees which led to the reports by the Burghard Committee and the BS9000 series of standards. Two sub-committees of BSI, TLE6/8 and TLE21/2 dealt respectively with r.f. and l.f. connectors and after early setbacks which were a result of the unfamiliar natur... View full abstract»

  • Noise limitations in digital recording

    Previous studies have shown that the tape limited signal/noise ratio (s.n.r.), which may be deduced from first principles, is in close agreement with practice on many modern recorders. This s.n.r. depends upon the medium properties and the recording format, in particular the trackwidth and bandwidth. Since the digital linear density usable is related to the bandwidth, it is possible to derive expr... View full abstract»

  • The thermal rating of metallized film capacitors under pulse conditions

    Publication Year: 1974, Page(s):218 - 226
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (903 KB)

    Simple expressions are derived for the power dissipation in metallized film capacitors under some common pulse current conditions. Using these, the sinusoidal current ratings may be used to estimate the suitability of the capacitors for pulse applications. Tables are given to facilitate the use of the results.
