STANDARD INDUCTANCE VALUE
The following standardization chart is offered
for your design and ordering convenience.
Each value listed is within one percent of the
preceding and succeeding values shown.
All decade multiples of these values, within the
range shown for each model in the chart, are
Vishay Dale standard values.
(Example: For a TE-2, 200µH, 20mH and
200mH are all decade multiples of 2.00 and
are all standard values.)
