Mike and all, Here's another item to add to the capacitor page. It's for those who've wondered why an X7R ceramic cap is better'n a Z5U ceramic cap... 73, Bob, WA9FBO _www.scomcontrollers.com_ (http://www.scomcontrollers.com)
EIA Three Digit "TC" Codes for Ceramic Capacitors Low Temperature Limit X = -55 C Y = -30 C Z = +10 C High Temperature Limit 5 = +85 C 6 = +105 C 7 = +125 C 8 = +150 C Maximum Allowable Capacitance Change From +25 C F = +/- 7.5% P = +/- 10% R = +/- 15% S = +/- 22% T = +22%/-33% U = +22%/-56% V = +22%/-82% Example: X7R = +/- 15% capacitance change over the temp range -55 C to +125 C. <BR><BR><BR>**************************************<BR> AOL now offers free email to everyone.
