content: Quote from: rolandpenplotter on January 22, 2014, 07:16:23 pmIll-conceived must be right. I did not mean to connect it to religion at all. I just thought "If we can't trust capacitor manufacturers, than whom can we trust" was a funny idea.You people are worse than I am!I'll discuss and argue about religion if there is an ongoing discussion because it interests me. And yes, I have strong opinions about it. But I don't live my life trying to find religious people with whom I can argue... capacitors aremuchmore interesting.

content: At least it has a value printed on it. Today I was wondering about the value of a leaky ceramic cap, then toasted it a little and reflowed it and the leakage dropped down by a lot. Thought about it for a minute then decided time to toss this ET remote transmitter fob and buy a new one. Standby 190uA, clean board and it is 30uA, toast the 2 larger ceramics and it is 9uA. So I have to go buy a new one, and open the gate motor......

It's a value, and it'll have a tolerance specified by the manufacturer. Exact same deal as with smd resistors. Do you also dislike printed values on smd resistors?

content: Quote from: rolandpenplotter on January 22, 2014, 06:53:42 pmAaah, yes. I believe the USA introduced this slogan on currency when they dropped the gold standard and replaced it with fiat. Despite the constitution seperating religion and state.Everyone used to trust the Federal Reserve to replace their paper notes with real gold at the standard. Now they can trust GOD for the value of worthless paper and nickel coins. Good Jaab! Clap Clap Clap!

content: Sorry to be OT (On Topic), but is there any chance you just have a defective cap, or do they mark other values that way also (e.g. 471 = 47pF)?

content: Itcouldbe defective, but it is so ridiculously close to 39pF that I seriously doubt it. Measured 38.9pF on a 1% LCR bridge with parasitic capacitance nulled.

content: Saint Vincent is the patron saint of wine and wine makers. Not really a frosty beverage but most wines are better served chilled than room temp. Yu Lu is often referred to has the patron saint of tea and the founding father of tea art. Will that suffice for hot beverages? (Got to love Google!)

content: Saint Christopher is the Patron Saint of Travelers. I know this because as an (16+) teenager I used to accompany my grandad on pub outings (I would drink Mild or Bitter). When he was told he had to give up alcohol due to blood pressure, etc, he found it highly amusing that the alcohol free beer in the local was called St. Christopher - ie. "Don't drink and drive!".I miss my old Grandad, he was a real mechanical engineer (Toolmaker) through and through. Lots of geek talk in the pub with him.
