Those values seem very large compared with what I see in products, 1 nF to 10 nF usually. Larger values are likely to resonate with self- inductance and stop being capacitors well below 30 MHz. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
