Standard Inductors
The Laboratory offers calibration of standard inductors in the range from 100 μH to 1 H.
Measurements are normally made at a nominal ambient temperature of 23 ¢J and unless otherwise specified, the test frequency will be 1 kHz. (Tests at 400 Hz and 10 kHz can be offered upon request.)
The inductor will be calibrated as a 2-terminal device and the series equivalent inductance of the device will be reported.
