  • n  an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current
  • n  an electrical device (typically a conducting coil) that introduces inductance into a circuit

  • Michael Idvorsky Pupin, Serb immigrant boy, now professor of electromechanics, Columbia University; inventor of electrical "tuning," the resonator, inductance coil, etc.
  • He would not divulge details, but indicated that he had mathematically discovered "a simple new combination of capacity and inductance that functions through properties of the .
  • Because of the double passage, the inductance was as low as Davis had hoped.

  • High-Temperature Inductors target automotive applications.
    Offered in 0750 and 1125 case sizes, respectively, IHTH-0750IZ-5A and IHTH-1125KZ-5A operate at up to +155°C with currents to 125 A and inductance values from 0.47–100 µH. With frequency range up to 10 MHz for some values, devices offer solution for voltage regulator modules and DC/DC converters. AEC-Q200-qualified inductors, housed in RoHS-compliant, lead-free shielded package, are suited ...

  • Microwave Chip Capacitors offer long-term stability.
    Consisting of Oxide/Nitride layer, Series 8000 offers working voltage >50 V and capacitance from 2.0–600 pF, while Series 8100 offers working voltage of more than 100 V and capacitance from 0.1–399 pF. Gold contacts are provided on front and back, and die thinness of as little as 3 mils is achievable for limiting inductance. Devices are suited for applications that require DC ...
