Manigandan, <bias alert> I am biased on this--because I wrote the book(s)--but I think that the best single source of information that you will find on capacitors is Robust Electronic Design Reference Book, chapter 8 (volume 1) and appendix D (volume 2). "Robust" just came out last Wednesday, March 24th ( http://www.r-e-d-inc.com/book-out.htm ). </bias alert> The second best single source of information that I know of on capacitors is The Capacitor Handbook by Cletus J. Kaiser, available from CJ Publishing, 2851 West 127th Street, Olathe, KS 66061 for $15.95 plus $4.00 shipping. Or you can buy his five-volume Discrete Library for $75.00 with free shipping, which includes: * The Diode Handbook. * The Transistor Handbook. * The Capacitor Handbook. * The Resistor Handbook. * The Inductor Handbook. Some other excellent sources of information on capacitors (references from the end of chapter 8 of "Robust") are: * Harper, Charles A., Handbook of Components for Electronics. New York: McGraw-Hill, 1977, pp. 7-4 to 7-6, 7-10 to 7-20, 8-1 to8-155. * Harper, Charles A., Passive Component Handbook, 2nd Edition. New York: McGraw-Hill, 1997, pp. 69 to 203. * Jones, Thomas H., Electronic Components Handbook. Reston, VA: Reston Publishing, 1978, pp. 1 to 77. * Levine, Sy, Basic Concepts and Passive Components. Plainview, NY: Electro-Horizons Publications. 1986, pp. 135 to 156. * Sinclair, Ian, Passive Components, a user's guide. Boston, MA: Newnes, 1991, pp. 91 to 126. * Sinclair, Ian, Passive Components for Circuit Design. Boston, MA: Newnes, 2001, pp. 89 to 124. For information sources available on the Internet, please look at my web page "POWER DISTRIBUTION ON PRINTED CIRCUIT BOARDS" at http://www.dbicorporation.com/pwr-bib.htm which includes URL's for many application notes, papers, design guides, etc. A lot of information on X2Y capacitors has just been published in the last four months, and thus didn't make it into "Robust". So the best sources for information on X2Y capacitors are: * http://www.x2y.com/ * http://www.amccaps.com/ * http://www.johansondielectrics.com/ * http://www.syfer.com/ * http://www.yageo.com/ John Barnes KS4GL, PE, NCE, ESDC Eng, SM IEEE dBi Corporation http://www.dbicorporation.com/ ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
