RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

ESL Calculation From Cap Datasheet - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

Post subject: ESL Calculation From Cap Datasheet
postPosted: Tue May 17, 2005 2:53 pm
to get a calculation of the ESL in some tantalum and/or C0G ceramic
Unfortunately, the manufacturers do not plot this data,
so I want to extrapolate the ESL using the Impedance vs. Frequency,
DF factor to get the ESR, and the capacitance then solving for the inductive
reactance and thus the series inductance at frequency omega.
Am I off base here??
Anyone have a better method?

Manufacturers almost always have more
data on their product than they print in datasheets. Have you tried
calling the applications engineering department of the various capacitor
suppliers and asking for the data you need?
was an applications engineer for a semiconductor company years ago,
so "your mileage may vary")

you propose doing is fine.
