Design and Development of High Frequency Standard Inductors

Abstract

A set of high frequency standard inductors having nominal values of 10µH, 100µH and 1000µH has been designed and developed. Such inductors which have been constructed by employing thin film resistors and high quality capacitors, show little variation at high frequencies. Also their terminals are provided with 4-TP (Four Terminal Pair) configuration which is capable of minimizing residual impedances and stray field effects at high frequencies. Due to

these features, these inductors serve as good inductance standards which ensures high accuracy at high frequencies upto about 10 MHz. As such these inductors would serve as chelon I level transfer standards at H.F. and are also quite suitable for calibration of 4-TP LCR  meters/impedance bridges.
