ESL Calculation From Cap Datasheet - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Post subject: ESL Calculation From Cap Datasheet
Unread postPosted: Tue May 17, 2005 2:53 pm

Hi All,

Im trying to get a calculation of the ESL in some tantalum and/or C0G ceramic caps.

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?

Good Luck!
(I was an applications engineer for a semiconductor company years ago, so "your mileage may vary")

What you propose doing is fine.
